A cavity-dumped and regenerative amplifier system for generating high-energy, high-repetition-rate picosecond pulses

摘要

We report a high-energy, high-repetition CW pumped Nd:YVO_4 amplifier system, that produces 10.5W, 14.2 ps pulses at 1064 nm wavelength and 5W pulses at 532 nm wavelength with a repetition rate of 10kHz. Pulses from a passively mode-locked Nd:YVO_4 oscillator are first generated by cavity dumping, and then further amplified in a regenerative amplifier from 545 nJ to 1 mJ with a CW diode-pumped Nd:YVO_4. After frequency doubling, 0.5 mJ pulses are obtained with a wavelength of 532 nm.
