A compact diode-pumped passively Q-switched laser has been demonstrated with a coated Cr4+YAG crystal as both a saturable absorber and an output coupler. When CW pumped with a fibrecoupled laser diode, the laser produces pulses of 5-30ns duration, with a repetition rate of 75-90kHz. The highest peak power was 430W. obtained at 1.6W of pump power, which is a 520 times enhancement in comparison to an output power of 830mW under CW operation.
