Abstract
We demonstrate amplification of picosecond laser pulses to at a pulse repetition frequency (PRF) from a two-stage cryogenic chirped-pulse Yb:YAG amplifier, composed of a regenerative amplifier (RGA) and a two-pass booster amplifier. The RGA produces of energy at PRF and at PRF with excellent energy stability (~0.3% rms) and beam quality (). Pulse stretching and compression are achieved by using a chirped fiber Bragg grating and a multilayer dielectric grating pair, respectively. Compressed pulses from the RGA are obtained with a throughput efficiency of ~80% (~6.5 mJ for ). The booster amplifier further amplifies the pulses to at PRF, and ~32 mJ, ~15 ps pulses are expected after compression. The amplifier chain seeded from a femtosecond Yb-fiber laser enables the optical self-synchronization between signal and pump in optical parametric chirped-pulse amplifier applications.
