摘要：
We demonstrate a high-repetition-rate, short-pulse-width pulse burst laser from a compact 885 nm laser diode directly pumped by a passively Q-switched YAG/Nd:YAG/Cr:YAG laser. We investigate the output laser characteristics with different output transmissions and spot sizes of the pumping laser and compare these characteristics. After optimization, we achieve a shortest pulse width of 1.4 ns generated by a 1,064 nm pulse burst laser. The single-pulse energy reaches 239 mu J at 86.3 kHz, with a peak power of 117.2 kW.
