Abstract

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 mrad and longitudinal mode selection was observed.
