Abstract

We report on development of a 100-kHz, 5-mJ picosecond system based on a two-stage thin-disk Yb:YAG regenerative amplifier. With a compact ring cavity, we obtained 565 W with 46.7% optical-to-optical efficiency in continuous-wave. In seeded operation, pulses with energy up to 4 mJ and 1.4-nm bandwidth were generated with 39% extraction efficiency. Pulse compression below 2 ps was so far demonstrated at lower pulse energy of 1 mJ. Full-power pulse compression and further pulse energy increase are under development.
