title: Ultrafast thin-disk Yb:KY(WO4)2 regenerative amplifier with a 200-kHz repetition rate.
abstract: We report an Yb:KYW thin-disk amplifier system that provides ultrashort pulses in the 10-microJ energy range at high repetition rates. The thin-disk concept uses large laser beam cross sections to avoid high peak intensities. Without using a traditional diffraction-grating stretcher, pulse energies of approximately 9 microJ with pulse durations of 280 fs at repetition rates of 200 kHz were generated.
