摘要：
An average power of 96 W pulse-bursts picosecond laser system at a pulse repetition frequency of 1 kHz was reported with six pulses in bursts. Pulses in bursts have equal spacing and amplitude; spacing between each pulse was 800 ps, which repetition rate was up to gigahertz. The beam quality of M-2 factor was less than 3, and pulse width was 50 ps. Pulses from a Nd: YVO4 mode-locked laser were broadened to 115 ps by a volume-Bragg grating and each pulse was divided into six pulses by beam splitter mirrors to obtain seed bursts. A Nd: YAG regenerative amplifier and two stages of single passed high gain Nd: YAG amplifier with serrated aperture were applied to achieve high power. (C) 2017 Optical Society of America
