A diode-pumped Nd: YAG laser at 1123 nm is passively Q-switched by using a low doping concentration Cr4+: YAG crystal as a saturable absorber. When pumped by a 1.5-W laser diode, the laser produces pulses of 50-ns duration with a pulse energy of as much as 15 μJ and a peak power of 300 W at a pulse-repetition rate of 10 kHz.
