    <title language="eng">Monitoring of the laser cleaning process of artificially soiled paper</title>
    <abstract language="eng">Laser cleaning of soiled paper is a challenging task due to the fact that a contamination has to be removed and a fragile organic material has to be preserved. The ejection of particles forms a significant channel for the removal of unwanted surface contaminations and can be exploited for an in-situ monitoring of the cleaning procedure. 532-nm-nanosecond single and multi pulse laser cleaning of artificially soiled Whatman© paper was performed. Particles were registered with a dust monitor. These in-situ experiments were combined with ex-situ investigations of cleaning and substrate damage thresholds by means of light and scanning electron microscopic techniques. The cleaning efficiency measured by a multi-spectral imaging system was compared to the in-situ particle monitoring. Additionally, possible color changes of the paper substrate were evaluated.</abstract>

    <title language="eng">Cleaning of artificially soiled paper with 532-nm nanosecond laser radiation</title>
    <abstract language="eng">Cleaning of paper is a challenging task due to the fact that a contamination should be removed and a fragile organic original material has to be preserved. Pulsed laser cleaning of artificially soiled Whatman© filter paper samples serving as models for historical paper was performed. Different cleaning strategies employing 8-ns laser pulses at 532 nm wavelength were applied to clean paper avoiding undesired effects like discoloration (yellowing) and mechanical deterioration of the substrate. Multi shot experiments with low-energy pulses were compared with single pulse investigations utilizing high pulse energies achieving a constant energy load incident on the samples in both cases. The cleaning efficiency and possible yellowing effects were evaluated by means of a multi spectral imaging system. An extensive microscopic analysis of the cleaned parts of the samples provided insight into the remaining soiling on the surface and in the bulk of the paper material after laser treatment. As a reference, a hard and a soft eraser were used to clean the samples.</abstract>

    <title language="eng">Influence of Technological Parameters on Nanosecond Laser-induced Surface Damage of Optical Multimode Fibers</title>
    <abstract language="eng">High-power optical multimode fibers are essential components for materials processing
and surgery and can limit the reliability of expensive systems due to breakdown at the end faces.
The breakdown threshold of fibers is determined by intrinsic materials properties and parameters of
the technology applied. The aim of this paper is the identification of technological parameters that
are crucial for the fiber quality.
Fibers were drawn from preforms of Heraeus SWU with core material F300 and a low amount of
OH-. Both, the cladding (fluorine doped SiO2) to core diameter ratio (CCDR) and the drawing speed
were varied. CCDR values between 1.05 and 1.4 were used. Afterwards, the laser-induced damage
thresholds (LIDT) of the fibers were determined. For comparison, also samples from preforms,
which underwent different thermal treatments above the transition temperature, were tested with
respect to their damage resistivity. Single and multi pulse LIDT measurements were done in
accordance with the relevant ISO standards. Nd:YAG laser pulses with durations of 15 ns (1064 nm
wavelength) and 8.5 ns (532 nm) at a repetition rate of 10 Hz were utilized. For the fibers, LIDT
values (1-on-1, 1064 nm and 532 nm) increased with growing CCDR and with decreasing drawing
velocities.</abstract>

An den zugehörigen Tagungen ist dies in der Liste der aufgenommenen Tagungen von Thomson/Reuters allerdings nicht sicher zu erkennen, da die Tagungsreihen nicht mit jedem Tagungsband in der Reihe erscheinen.  Die Zuordnung zur 1000-Euro-Liste geschieht am sichersten, wenn die Einträge als Zeitschriftenartikel in der als ZEITSCHRIFT aufgenommenen Reihe "Advanced Materials Research" eingegeben werden. Die Reihe besitzt eine ISSN und ist auch in der EZB als elektronische Zeitschrift aufgenommen, so dass diese Interpretation mit anderen Quellen konform ist.  Die Angaben für "Erscheinungsort", "Verlag" und "Erscheinungsverlauf" stimmen nicht mit den Angaben in der ZDB überein, die falsch zu sein scheinen. Sie wurden anhand des Online-Katalogs der TIB Hannover ermittelt, indem die individuellen Bände der Buchreihe aufgerufen wurden. Da der konkrete Ort von Band zu Band variiert, (z. B. "Uetikon", "Stafa" und "Durnten") wurde "Zurich" als Ort gewählt, obwohl es sich korrekterweise nur um den Kanton Zürich handelt, und nicht die Stadt.  Jan Harloff-Puhr, 17.12.2013</enrichment>

    <title language="eng">Breakdown limits of optical multimode fibers for the application of nanosecond laser pulses at 532 nm and 1064 nm wavelength</title>
    <abstract language="eng">For many applications, optical multimode fibers are used for the transmission of powerful laser radiation. High light throughput and damage resistance are desirable. Laser-induced breakdown at the end faces of fibers can limit their performance. Therefore, the determination of laser-induced damage thresholds (LIDT) at the surface of fibers is essential.&#13;
Nanosecond (1064 nm and 532 nm wavelength) single-shot LIDT were measured according to the relevant standard on SiO2 glass preforms (Suprasil F300) as basic materials of the corresponding fibers. For 10 kinds of fused silica fibers (FiberTech) with core diameters between 180 µm and 600 µm, an illumination approach utilizing a stepwise increase of the laser fluence on a single spot was used. For both wavelengths, the LIDT values (0% damage probability) obtained by means of the two methods were compared. The influence of surface preparation (polishing) on damage resistance was investigated. For equal surface finishing, a correlation between drawing speed of the fibers and their surface LIDT values was found. In addition to the surface measurements, bulk LIDT were determined for the preform material.</abstract>

    <title language="deu">Laserreinigung von künstlich verschmutzten europäischen Papieren des 19. Jahrhunderts</title>
    <abstract language="deu">Diese Arbeit beschreibt die Laserreinigung von gebräuchlichen Papieren des 19. Jahrhunderts in Kombination mit zwei Schmutzvarianten. Aufgrund der weiten Verbreitung in Bibliotheken und Kunstsammlungen wurden Hadernpapier und holzhaltiges Papier ausgewählt. Als Referenz diente Whatman-Filterpapier. Zur künstlichen Verschmutzung wurden Zeichenkohle oder Standardschmutz (Standard Test Dust SAE J 726 fine, mit Flammruß im Verhältnis 20:1 gemischt) mit Hilfe von Pinsel und Staubsauger jeweils auf die drei Papierarten aufgetragen und in den Faserverbund eingesaugt. Die Nutzung von Modellproben erweist sich für grundlegende Untersuchungen als vorteilhaft, da das Vorhandensein hinreichend großer Flächen (gleichartiger Objekte) für einen Vergleich mit Ergebnissen klassischer Reinigungstechniken unabdingbar ist. Die preiswerten Proben erlauben darüber hinaus auch die Anwendung zerstörender Analysetechniken. 

Für die Laserreinigungsexperimente wurde ein Nd:YAG-Laser mit Impulsdauern in der Größenordnung von 10 ns bei 532 nm Wellenlänge und einer Repetitionsrate von 500 Hz verwendet. Die Laser-Bearbeitungsstation erlaubt die flächige Bearbeitung von Objekten, wobei der Laserstrahl bewegt wird. Der Laser wird mittels Computer ferngesteuert und unter Klasse-1-Sicherheitsbedingungen betrieben. Bei der Untersuchung der Modellproben wurde jeweils die Anzahl der Impulse pro Probenstelle sowie die Laser-Energiedichte variiert. Ziel der Arbeiten war die Ermittlung eines Laser-Arbeitsbereiches für die Reinigung der verschiedenen Papierproben. Die Modellobjekte wurden vor und nach der Laserbehandlung mittels lichtmikroskopischer, rasterelektronenmikroskopischer und colorimetrischer Analysemethoden untersucht.</abstract>

    <abstract language="eng">This contribution compares traditional cleaning and laser methods. Partial laser cleaning with a nanosecond pulse laser (wavelength of 532 nm) has proved very promising for future application in paper conservation-restoration. Traditional cleaning methods are not always sufficient or successful in surface cleaning of objects of art. Comparative studies of traditional paper cleaning methods and laser cleaning were made on several historic picture postcards printed with the chromolithography technique.</abstract>

    <title language="eng">Laser cleaning of artificially soiled paper</title>
    <abstract language="eng">Laser cleaning for works of art on paper might be a supplemental, noncontact method to overcome some of the limitations of traditional dry cleaning techniques. Three different types of paper (pure-cellulose filter paper, rag paper, and wood-pulp paper) were mechanically soiled with pulverized charcoal in a standardized procedure to make model samples. These samples were characterized microscopically and by means of lightness measurements using a multi-spectral imaging system. A prototype laser workstation with Laser Class I conditions for the operator was used for the cleaning experiments. For 10-ns laser pulses at a wavelength of 532 nm, a set of laser parameters was established for a successful cleaning of the samples avoiding damage to the paper substrate. Single- and multi-pulse illumination conditions were tested. An extensive microscopic analysis after laser treatment of the cleaned parts of the samples provided insight into the remaining soiling on the surface and in the bulk of the paper material.</abstract>

    <title language="eng">Probing the heat affected zone by chemical modifications in femtosecond pulse laser ablation of titanium nitride films in air</title>
    <abstract language="eng">A new approach is presented to quantify the so-called "heat affected zone" (HAZ) during
femtosecond laser pulse processing. Ablation of titanium nitride (TiN) thin films (~3 μm
thickness) by multiple femtosecond laser pulses (τ=130 fs, λ=800 nm) in air environment was
studied by means of two different surface analytical methods both being sensitive to chemical
alterations at the surface. Scanning Auger electron microscopy was applied for a visualization of the
spatial distribution of specific elements (Ti, O) within the laser-modified areas. The chemical state
of the irradiated surface was revealed by complementary x-ray photoelectron spectroscopy. Both
methods were used for a depth-profiling chemical analysis (tracking the elements Ti, N, O, and C)
using an Ar-ion beam for surface sputtering. In a narrow laser fluence range slightly below the
ablation threshold of TiN significant superficial oxidation can be observed leading to the formation
of substoichiometric TiO2-x. At fluences above the ablation threshold, an increased titanium
concentration is observed within the entire ablation craters. Following upon sputter removal the
elemental distribution into the depth of the nonablated material, the results allow an estimation of
the heat-affected zone for femtosecond laser ablation in air environment. According to our analyses,
the HAZ extends up to a few hundreds of nanometers into the nonablated material.</abstract>

    <abstract language="eng">Single and multi pulse laser-induced damage thresholds (LIDT) of core, cladding, and coating materials of high-power
optical multimode fibers were determined in accordance with ISO 11254 for 532 nm and 1064 nm wavelength in the 10-ns
pulse duration regime with spatial Gaussian beam shape. For all-silica fibers, LIDT increases with rising core diameter in a range between 100-600 µm for a constant cladding-core ratio of 1.2. The damage resistance of the low refracting cladding (0.3 % fluorine doped fused silica) is comparable to the undoped SiO2 core. Coating materials show significantly lower LIDT than light-guiding parts of the fibers.</abstract>

    <abstract language="eng">Hydrogenated amorphous carbon layers were deposited on BK7 glass in a plasma-assisted chemical vapor deposition
process. Low and high refracting films with thicknesses d ranging from 11 nm to 5.8 µm were produced having refractive

    <title language="eng">Femtosecond laser-induced periodic surface structures: recent approaches to explain their sub-wavelength periodicities</title>
    <abstract language="eng">The formation of laser-induced periodic surface structures (LIPSS) upon irradiation of semiconductors and dielectrics by linearly polarized high-intensity Ti:sapphire fs-laser pulses (τ ~100 fs, λ ~800 nm) is studied experimentally and theoretically. In the experiments, two different types of LIPSS exhibiting very different spatial periods are observed (socalled LSFL  low spatial frequency LIPSS, and HSFL - high spatial frequency LIPSS), both having a different dependence on the incident laser fluence and pulse number per spot. The experimental results are analyzed by means of a new theoretical approach, which combines the generally accepted LIPSS theory of J. E. Sipe and co-workers [Phys. Rev. B 27, 1141-1154 (1983)] with a Drude model, in order to account for transient changes of the optical properties of the irradiated materials. The joint Sipe-Drude model is capable of explaining numerous aspects of fs-LIPSS formation, i.e., the orientation of the LIPSS, their fluence dependence as well as their spatial periods. The latter aspect is specifically demonstrated for silicon crystals, which show experimental LSFL periods Λ somewhat smaller than λ. This behaviour is caused by the excitation of surface plasmon polaritons, SPP, (once the initially semiconducting material turns to a metallic state upon formation of a dense free-electron-plasma in the material) and the subsequent interference between its electrical fields with that of the incident laser beam, resulting in a spatially modulated energy deposition at the surface.&#13;
Upon multi-pulse irradiation, a feedback mechanism, caused by the redshift of the resonance in a grating-assisted SPP excitation, is further reducing the LSFL spatial periods. The SPP-based mechanism of LSFL successfully explains the remarkably large range of LSFL periods between ~0.6 λ and λ.</abstract>

    <title language="eng">Cleaning of soiled paper model samples using short and ultrashort laser pulses</title>
    <abstract language="eng">Paper is one of the most important materials representing and witnessing human culture particularly as a carrier medium for text and image. As soiling hampers the reception of information, paper cleaning techniques are needed. Traditional mechanical and chemical cleaning methods are used by conservator-restorers. In some cases, a classical cleaning procedure of paper objects yields unsatisfactory results or a conventional treatment is even impossible. Especially, fragile paper objects cause problems due to mechanical instabilities. Laser cleaning as a non-contact method might be a way to overcome some of the limitations of classical cleaning techniques. Laser parameters have to be chosen to achieve removal of the soiling without influencing the artwork. Any immediate as well as long-term effects causing an irreversible change of the artwork have to be avoided. At present, most laser applications are found in stone and metal conservation, while laser treatment of complex organic materials like paper is still not fully developed for application in conservators' workshops. This contribution describes recent work of pulsed laser cleaning of soiled model samples. Pure cellulose, rag paper and wood-pulp paper were mechanically soiled with pulverized charcoal in a standardized procedure to make model samples representing essential characteristics of contaminated real-world artworks. Afterwards, model samples were cleaned using short and ultrashort laser pulses in the nanosecond and femtosecond time domain, respectively. An extensive analysis of the model samples after laser treatment using an optical microscope and a multi-spectral imaging system allows a comparison of the cleaning results obtained with both laser sources.</abstract>

    <title language="eng">Implications of transient changes of optical and surface properties of solids during femtosecond laser pulse irradiation to the formation of laser-induced periodic surface structures</title>
    <abstract language="eng">The formation of laser-induced periodic surface structures (LIPSS) upon irradiation of silicon wafer surfaces by linearly polarized Ti:sapphire femtosecond laser pulses (pulse duration 130 fs, central wavelength 800 nm) is studied experimentally and theoretically. In the experiments, so-called low-spatial frequency LIPSS (LSFL) were found with periods smaller than the laser wavelength and an orientation perpendicular to the polarization. The experimental results are analyzed by means of a new theoretical approach, which combines the widely accepted LIPSS theory of Sipe et al. with a Drude model, in order to account for transient (intra-pulse) changes of the optical properties of the irradiated materials. It is found that the LSFL formation is caused by the excitation of surface plasmon polaritons, SPPs, once the initially semiconducting material turns to a metallic state upon formation of a dense free-electron-plasma in the material and the subsequent interference between its electrical field with that of the incident laser beam resulting in a spatially modulated energy deposition at the surface. Moreover, the influence of the laser-excited carrier density and the role of the feedback upon the multi-pulse irradiation and its relation to the excitation of SPP in a grating-like surface structure is discussed.</abstract>

    <title language="eng">Fixation of bioactive calcium alkali phosphate on Ti6Al4V implant material with femtosecond laser pulses</title>
    <abstract language="eng">Bone implants made of metal, often titanium or the titanium alloy Ti6Al4V, need to be surface treated to become bioactive. This enables the formation of a firm and durable connection of the prosthesis with the living bone. We present a new method to uniformly cover Ti6Al4V with a thin layer of ceramics that imitates bone material. These calcium alkali phosphates, called GB14 and Ca10, are applied to the metal by dip coating of metal plates into an aqueous slurry containing the fine ceramic powder. The dried samples are illuminated with the 790 nm radiation of a pulsed femtosecond laser. If the laser fluence is set to a value just below the ablation threshold of the ceramic (ca. 0.4 J/cm²) the 30 fs laser pulses penetrate the partly transparent ceramic layer of 20–40 µm thickness. The remaining laser fluence at the ceramic–metal interface is still high enough to generate a thin metal melt layer leading to the ceramic fixation on the metal. The laser processing step is only possible because Ti6Al4V has a lower ablation threshold (between 0.1 and 0.15 J/cm²) than the ceramic material. After laser treatment in a fluence range between 0.1 and 0.4 J/cm², only the particles in contact with the metal withstand a post-laser treatment (ultrasonic cleaning). The non-irradiated rest of the layer is washed off. In this work, we present results of a successful ceramic fixation extending over larger areas. This is fundamental for future applications of arbitrarily shaped implants.</abstract>

    <title language="eng">The influence of paper type and state of degradation on laser cleaning of artificially soiled paper</title>
    <abstract language="eng">Lasers can be a supplemental tool for restorers to overcome some of the limitations of traditional dry cleaning techniques for works of art on paper. The laser working range has to be optimized allowing for safe removal of contamination and limitation of damage to the substrate. This paper addresses the influence of paper type and state of degradation on laser working range. Three types of new paper (pure cellulose, bleached pulp paper, rag paper) were degraded and characterized with respect their degree of polymerization. Laser-induced damage thresholds of new and degraded paper were determined using SEM and viscometry. Additionally, artificially soiled model samples were made using two kinds of soiling, namely pulverized charcoal and soot-blackened standard test dust. Cleaning thresholds of soiled paper samples were evaluated. A working range for all combinations of paper and soiling between 0.05 J/cm2 and 0.5 J/cm2 was found for the application of 8-ns laser pulses at 532 nm wavelength.</abstract>

    <title language="eng">On the role of surface plasmon polaritons in the formation of laser-induced periodic surface structures upon irradiation of silicon by femtosecond-laser pulses</title>
    <abstract language="eng">The formation of nearly wavelength-sized laser-induced periodic surface structures (LIPSSs) on single-crystalline silicon upon irradiation with single or multiple femtosecond-laser pulses (pulse duration τ=130  fs and central wavelength λ=800  nm) in air is studied experimentally and theoretically. In our theoretical approach, we model the LIPSS formation by combining the generally accepted first-principles theory of Sipe and co-workers with a Drude model in order to account for transient intrapulse changes in the optical properties of the material due to the excitation of a dense electron-hole plasma. Our results are capable to explain quantitatively the spatial periods of the LIPSSs being somewhat smaller than the laser wavelength, their orientation perpendicular to the laser beam polarization, and their characteristic fluence dependence. Moreover, evidence is presented that surface plasmon polaritons play a dominant role during the initial stage of near-wavelength-sized periodic surface structures in femtosecond-laser irradiated silicon, and it is demonstrated that these LIPSSs can be formed in silicon upon irradiation by single femtosecond-laser pulses.</abstract>

    <title language="eng">Cleaning of artificially soiled paper using nanosecond, picosecond and femtosecond laser pulses</title>
    <abstract language="eng">Cleaning of cultural assets, especially fragile
organic materials like paper, is a part of the conservation
process. Laser radiation as a non-contact tool offers
prospects for that purpose. For the studies presented here,
paper model samples were prepared using three different paper
types (pure cellulose, rag paper, and wood-pulp paper).
Pure cellulose serves as reference material. Rag and woodpulp
paper represent essential characteristics of the basic
materials of real-world artworks. The papers were mechanically
soiled employing pulverized charcoal. Pure and artificially soiled paper samples were treated with laser pulses of
28 fs (800 nm wavelength) and 8–12 ns (532 nm) duration in
a multi pulse approach. Additionally, the cellulose reference
material was processed with 30 ps (532 nm) laser pulses.
Damage and cleaning thresholds of pure and soiled paper
were determined for the different laser regimes. Laser working
ranges allowing for removal of contamination and avoiding
permanent modification to the substrate were found.
The specimens prior and after laser illumination were characterized
by light-optical microscopy (OM) and scanning
electron microscopy (SEM) as well as multi spectral imaging
analysis. The work extends previous nanosecond laser
cleaning investigations on paper into the ultra-short pulse
duration domain.</abstract>

    <title language="eng">Damage mechanisms in polymers upon NIR femtosecond pulse laser irradiation: sub-threshold processes and their implications for laser safety applications</title>
    <abstract language="eng">This contribution investigates laser-induced damage of thin film and bulk polymer
samples, with the focus on physical processes occurring close to the damage threshold. In-situ
real-time reflectivity (RTR) measurements with picosecond (ps) and nanosecond (ns) temporal
resolution were performed on thin polymer films on a timescale up to a few microseconds (µs).
A model for polymer thin film damage is presented, indicating that irreversible chemical
modification processes take place already below the fluence threshold for macroscopic damage.
On dye-doped bulk polymer filters (as used for laser goggles), transmission studies using fs-and
ps-laser pulses reveal the optical saturation behavior of the material and its relation to the
threshold of permanent damage. Implications of the sub-threshold processes for laser safety
applications will be discussed for thin film and bulk polymer damage.</abstract>

    <title language="eng">Ultrashort Pulse Laser Interaction with Dielectrics and Polymers</title>
    <abstract language="eng">Abstract Femtosecond laser micromachining has excited vivid attention in various industri-
al fields and in medicine owing to the advantages of ultrashort laser pulses compared to
long-pulse treatment.These are mainly the reduction of the laser fluence needed to induce
ablation and the improvement of the contour sharpness of the laser-generated structures.
Recently,special attention was paid to femtosecond laser experiments on nonabsorbing in-
organic dielectrics.This is due to the fact that optical damage in dielectric optical elements
limits the performance of high-power laser systems.Despite the fact that a large variety of
organic polymers can be machined with excimer lasers successfully,the involvement of
thermal processes can lead to an unsatisfactory quality of the structures.Ultrashort,fs-laser
pulses might be an alternative for the treatment of polymers.Therefore,femtosecond laser
machining investigations of dielectrics and polymers are reviewed in this paper.Similarities
and differences of the ablation behavior of both material classes are discussed.The influ-
ence of the bandgap on the ablation threshold in dependence on the pulse duration,the en-
hancement of the machining precision with a shortening of the pulse duration,incubation
phenomena,and morphological features appearing on the surface after femtosecond laser
treatment are mentioned.Possible applications,e.g.,in medicine and biosensors,are de-
scribed.</abstract>

    <title language="eng">Primary hazards and reliability of protective materials</title>
    <abstract language="eng">Femtosecond laser pulses are close to industrial use. The advantages of ultrashort laser pulses for micromachining applications especially in the case of dielectric and biological samples down to pulse durations of 5 fs have been established. The current international standards of laser safety are primarily concerned with CW and pulsed lasers down to the nanosecond range. Therefore, human tissue and laser-protection equipment was investigated with respect to its resistance and protection performance for femtosecond laser illumination down to 30 fs. This included filter glasses for laser protection eyewear, polymer and textile materials used in curtains and guards. Bulk absorber filters can provide enough protection against laser radiation, give a sufficiently broad absorption spectrum. Materials are damaged more easily by femtosecond laser radiation. The need for sufficient spectral broadness as well as the different damage thresholds have to be included in international laser safety standards. This work should trigger the development of novel eye-protection devices that are lighter and ergonomically more acceptable than present commercial models.</abstract>

    <title language="eng">Femtosecond laser damage in dielectric coatings</title>
    <abstract language="eng">Multi-shot investigations of Ti:sapphire laser (wavelength (lambda) approximately equals 800 nm) induced damage were performed in three different laboratories (BAM, Berlin; LZH, Hannover; UNM, Albuquerque). The ablation behavior of a high reflecting mirror consisting of alternating (lambda) /4- layers of Ta2O5 and SiO2 was studied. Fused silica served as substrate. The influence of the pulse duration ((tau) equals 13 - 130 fs), the pulse number (30 - (infinity) ) and the repetition rate (10 Hz - 100 MHz) on the damage threshold will be discussed.</abstract>

    <title language="eng">Femtosecond pulse laser ablation of anodic oxide coatings on aluminium alloys with on-line acoustic observation</title>
    <abstract language="eng">The 125-fs laser ablation behaviour (800 nm) of aluminium and anodic oxide coatings on an AlMgSi1 alloy was investigated. The multi-pulse ablation threshold of aluminium at 1.2 J cm-2 was less than that of the oxides of 23 J cm-2. Aluminium exhibited a single pulse modification (melting) threshold of 0.3 J cm-2. These values derived from an evaluation of the crater geometry coincided with on-line acoustic measurements. The detected microphone voltage amplitude increased linearly with the laser fluence. The morphology of the ablation craters on aluminium indicated melt formation and displacement of a homogeneous melt phase due to the recoil action of the expanding metal vapour. The laser-processed ceramic oxide phases, on the other hand, showed a spongy resolidified melt layer, which denotes a collocated in-depth formation both of a melt and a gas phase. These phenomena are discussed in terms of the relative dominance of penetration depth of laser light and heat affected zones in the investigated materials with strongly varying optical and thermodynamical properties.</abstract>

    <title language="eng">Femtosecond laser ablation of silicon-modification thresholds and morphology</title>
    <abstract language="eng">We investigated the initial modification and ablation of crystalline silicon with single and multiple Ti:sapphire laser pulses of 5 to 400 fs duration. In accordance with earlier established models, we found the phenomena amorphization, melting, re-crystallization, nucleated vaporization, and ablation to occur with increasing laser fluence down to the shortest pulse durations. We noticed new morphological features (bubbles) as well as familiar ones (ripples, columns). A nearly constant ablation threshold fluence on the order of 0.2 J/cm2 for all pulse durations and multiple-pulse irradiation was observed. For a duration of ,100 fs, significant incubation can be observed, whereas for 5 fs pulses, the ablation threshold does not depend on the pulse number within the experimental error. For micromachining of silicon, a pulse duration of less than 500 fs is not advantageous.</abstract>

    <title language="eng">Laser ablation thresholds of silicon for different pulse durations: theory and experiment</title>
    <abstract language="eng">The ultrafast laser ablation of silicon has been investigated experimentally and theoretically. The theoretical description is based on molecular dynamics (MD) simulations combined with a microscopic electronic model. We determine the thresholds of melting and ablation for two different pulse durations =20 and 500 fs. Experiments have been performed using 100 Ti:Sap-phire laser pulses per spot in air environment. The ablation thresholds were determined for pulses with a duration of 25 and 400 fs, respectively. Good agreement is obtained between theory and experiment.</abstract>
