Abstract
We report an Yb:KYW thin-disk amplifier system that provides ultrashort pulses in the 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 with pulse durations of 280 fs at repetition rates of 200 kHz were generated.
