Abstract
Laser-diode pumped passively Q-switched single-frequency Nd:YAG laser has b een demonstrated with a Cr4+:YAG crystal as the saturable absorber. When pu mped with a fiber-coupled CW laser diode, the laser produces pulses of 1.4- 20.9 ns duration, with a repetition rate of 1.9-52.0 kHz. The highest peak power of 17.6 kW was obtained at an incident pump power of 1.8 W. The use o f a Cr4+:YAG saturable absorber enables the laser to operate not only in a single-frequency mode but also linearly polarized. The mode selection mecha nism is discussed.
