摘要：
Passive Q-switching of high power CW pumped Nd:YAG laser by using phototropic Cr4+ ion centers in YAG was investigated in detail. Over 180 W average output was obtained at 15 kW input power with two cavities. The Q-switch efficiency is about 70 %. The beam parameter product is 7.5 mm mad and longitudinal mode selection was observed.
