摘要
1／4波片在Nd:YAG激光器谐振腔内有多种应用,其作用由其在谐振腔内的位置和快轴方向决定。本文以一种电光调Q脉冲Nd:YAG激光器谐振腔为例,详细分析了1／4波片在谐振腔内的各种应用,并提出通过调节1／4波片的快轴方向来控制激光器偏振方向的方法。
A quarter wave plate （QWP） is frequently used in a pulse Nd ： YAG laser resonator and its function is determined by its location and the direction of the fast axis in the resonator. This paper gives a detailed analysis of the application of QWP in a typical pulse Nd ： YAG laser resonator. Particularly, a method to control the polarization of the laser beam by adjusting the fast axis direction of QWP is proposed.
