A method of Q-switching is described in which two Fabry-Perot etalons replace the output mirror of the laser resonator. The etalons behave as a variable output coupler and the system will Q-switch if the optical spacing of one of the etalons is changed sufficiently rapidly. A number of mechanisms which limit the hold-off power of the switch are discussed, and experiments with a continuously pumped Nd/YAG laser are reported. Repetitive Q-switching was demonstrated by changing the output etalon spacing with a piezoelectric transducer.
描述了一种调Q方法，其中两个法布里-珀罗标准具取代了激光谐振器的输出镜。这些标准具起到可变输出耦合器的作用，并且如果其中一个标准具的光学间距变化足够快，系统将进行调Q。讨论了一些限制开关保持功率的机制，并报告了用连续泵浦的Nd/YAG激光器进行的实验。通过用压电换能器改变输出标准具的间距，演示了重复调Q。
