    <title language="eng">Cutting and Drilling of SiC Semiconductor by Fiber Laser</title>
    <abstract language="eng">We present an experimental study on fiber laser micromachining of 4H-SiC semiconductor. In particular, we optimize the process time for percussion drilling of 440 µm and 330 µm thick wafers with a minimum drilling time of, eg, 7.5 ms being achieved for 330 µm thick wafers. The drilled holes are characterized by a low taper, a high circularity and entry diameters of about 60 µm. For laser cutting, effective cutting speeds of 2 mm/s and 0.63 mm/s are obtained for 330 µm and 440 µm wafer thickness, respectively, with the cut kerf width being 65 µm. Both processes are associated with a good quality that is characterized by no chipping and cracks. The capability of the fiber laser based micromachining process is highlighted by cutting complex micrometer scale inner and outer contours into partially metallized SiC wafers with high quality.</abstract>

    <title language="eng">Image Processing Algorithm for In Situ Monitoring Fiber Laser Remote Cutting by a High-Speed Camera</title>
    <abstract language="eng">We present an in situ process monitoring approach for remote fiber laser cutting, which is based on evaluating images from a high-speed camera. A specifically designed image processing algorithm allows the distinction between complete and incomplete cuts by analyzing spectral and geometric information of the melt pool from the captured images of the high-speed camera. The camera-based monitoring system itself is fit to a conventional laser deflection unit for use with high-power fiber lasers, with the optical detection path being coaxially aligned to the incident laser. Without external illumination, the radiation of the melt from the process zone is recorded in the visible spectral range from the top view and spatially and temporally resolved. The melt pool size and emitted sparks are evaluated in dependence of machining parameters such as feed rate, cycles, and focus position during cutting electrical sheets.</abstract>
