摘要：

Repetitively Q-switched operation of an end-pumped Nd:YAG laser over the range of 200 Hz to 3 kHz using an intracavity chopper is demonstrated. Performance is shown to be comparable to that achieved with an acousto-optic Q switch under similar conditions. The advantages and limitations of the mechanical Q switch are described. Parametric variations of output coupling and pump power lead to an extended empirical description of repetitively Q-switched laser operation. The insertion loss as a function of aperture-edge penetration into the resonator is reported, and a definition of the mechanical Q-switch opening time is provided. Q-switched pulsewidths as short as 35 ns were obtained for the Nd:YAG laser, with a peak power-enhancement factor in excess of 300.
