Zusammenfassung:
A highly stable Yb:KYW based dual crystal regenerative
amplifier is demonstrated, which generates at 1 kHz 6.5-mJ pulses before
and up to 4.7-mJ sub-ps pulses after compression with multilayer-dielectric
gratings, respectively. The stretcher is compact and based on chirped-fiber
Bragg gratings. In continuous-wave operation, 20 W are extracted with a
slope efficiency of 40%. The experimental data are in agreement with
detailed simulations of the laser dynamics.
