摘要：
In this paper, a high average power passively Q-switched, laser diode side-pumped green laser at 532 nm was reported by using Nd:YAG/Cr4+:YAG/YAG composite crystal for the first time. The performances of the average power, pulse width, and pulse repetition rate on pump power were measured. Under the pump power of 187.5 W, the Q-switched green laser was obtained with the average power of 27.2 W, pulse width of 210 ns, and the repetition rate of 21.2 kHz. The single-pulse energy was 1.28 mJ and peak power was higher than 6.1 kW. (C) 2014 Laser Institute of America.
