theoretical analysis of polarization tracking based on half-wave plate

基于半波片的偏振跟踪理论分析

A novel 2 × 2 optical switch, which consists of phase spatial light modulator ( PSLM), polarizing beam-splitter ( PBS), mirror, half-wave plate ( HWP) and quarter-wave plate ( QWP), is proposed.

设计了一种由相位型空间光调制器（PSLM）、偏振光分束器（PBS）、反射镜、半波片（HWP）和四分之一波片（QWP）构成的2×2光开关。

A 946 nm Nd: YAG laser pumped by a laser diode was obtained using four mirrors ring resonator. the laser was single-frequency operated by using a TGG and a half-wave plate acted as optical diode in the cavity.

用激光二极管（LD）抽运Nd：YAG晶体，采用四镜环行腔，腔内放置TGG晶体和λ/2波片，组成光学单向器，利用LBO晶体内腔倍频技术，实现单频946nm红外光和473nm蓝光输出。
