Abstract

In this contribution, we report on development of a high-repetition-rate, kW-level picosecond Yb:YAG thin-disk laser system PERLA C [1]. Its design utilizes the CPA (Chirped Pulse Amplification) technique, comprising a low-energy Yb-fiber oscillator and preamplifiers, two thin-disk regenerative amplifiers and a chirped volume Bragg grating (CVBG) for both pulse stretcher and compressor. The target parameters of this system are 5-mJ pulse energy at 100 kHz repetition rate (500 W average power) and pulse duration below 2 ps, with possibility to adjust the repetition rate of the system from 50 kHz to 1 MHz while maintaining approximately the average power. Prospectively, we plan to upgrade the system to 1-kW average power level.
