Thin-disk multipass amplifier for kilowatt-class ultrafast lasers above 100 mJ

We present a linear multipass amplifier based on the thin-disk technology which allows power scaling of continuous-wave, pulsed, and ultrashort-pulsed lasers without change of beam characteristics. The flexibility of the seed laser, such as choice of repetition rate, pulse duration, and bursts is maintained. Due to a large beam radius on the thin disk of several millimeters, peak intensities are l...
