    <title language="eng">Laser turning with ultrashort laser pulses</title>
    <abstract language="eng">We report on a comprehensive micromachining study of rotationally symmetric parts using femtosecond laser. A&#13;
laser turning process with tangential impingement of the laser radiation complemented by a trepanning optics is&#13;
implemented as to accomplish a true laser lathe micromachining approach. With the objective of optimized&#13;
ablation rate and reduced surface roughness, the influence of pulse energy, feed rate, trepanning diameter and&#13;
angular beam incidence, respectively, is investigated for processing stellite rods. We find the smallest feasible&#13;
feature sizes of 8.5 μm in diameter and smoothest surfaces with an arithmetic average of the roughness profile as&#13;
low as 0.18 μm. The surface roughness, however, appears to be limited by the occurrence of laser induced periodic&#13;
surface structures provoked by the femtosecond laser radiation. Furthermore, the variation of the fluence&#13;
in accordance to the incidence on a curved surface is discussed and the heat input into the material is examined&#13;
through a longitudinal cross section.</abstract>

    <title language="eng">Microchannels inside bulk PMMA generated by femtosecond laser using adaptive beam shaping</title>
    <abstract language="eng">In this contribution, we report on the generation of internal microchannels with basically unlimited channel length inside of PMMA bulk material by femtosecond laser. A precisely controllable and stable circular channel cross section is obtained by using a spatial light modulator to compensate the writing depth depending spherical aberration. Furthermore, the generation of a rotatable elliptical input beam by adaptive optics ensures a fitting of the beam shaping to the writing direction. In this study, we report on both, the effect of the ellipticity of the input beam and the effect of a correction of the spherical aberration on the circularity of the resulting internal microchannels. Moreover, we demonstrate the application of this writing technique by creating microfluidic testing structures inside of a transparent standard polymer.</abstract>

    <title language="eng">Ultrashort pulse laser micro-welding of cyclo-olefin copolymers</title>
    <abstract language="eng">We report on the joining of transparent thermoplastic polymers using infrared femtosecond laser pulses. Due to nonlinear absorption, the developed micro-welding process for cyclo-olefin copolymers does not require any intermediate absorbing layers or any surface pre-processing of the welding partners. In view of an optimized and stable micro-welding process, the influence of the welding speed and focal position on both, the quality and shear force strength are investigated. We highlight that welding seam widths of down to 65 µm are feasible for welding speeds of up to 75 mm/s. However, a variation of the welding speed affects the required focal position for a successful joining process. The shear force strength of the welding seam is determined to 37 MPa, which corresponds to 64% of the shear strength of the bulk material and is not affected by the welding speed.</abstract>
