A Compact Yb:YAG thin-disk regenerative amplifier utilizing a chirped volume Bragg grating (CVBG) as a pump source for anOPCPA amplifier at ELI-Beamlines is demonstrated. As a compact and stable stretcher, a chirped fiber Bragg grating (CFBG) followed by a CVBG is used. After amplification to 24 mJ, pulses are compressed to 2 ps in the CVBG and a short grating compressor; this allows the system to be compact while avoiding the SPM which comes from highly compressed pulses within the CVBG. The compact setup fits into a box 1200x600 mm2 large, which includes the regenerative amplifier, grating compressor, and second harmonic assembly.
