摘要

We present a results of dual-crystal Yb:KGW laser development that is capable to operate as a actively Q-switched oscillator with output power up to 24 W and pulse length of 20 ns, or as a regenerative amplifier with output power up to 21 W and pulse duration below 200 fs after compression of chirped pulses. Both lasers have excellent beam quality with beam parameter M2<;1.2. We discuss some aspects of the design and performance optimization of dual-crystal Yb:KGW laser system.
