摘要
理论上推导出了环形激光器对S光和P光相位延迟差与其拍频峰对应的压电陶瓷电压差的关系式,分析了方形环形激光器对S光和P光的频率响应特性,通过测量拍频峰电压差实现环形激光器反射镜相位延迟差测量。通过搭建环形激光器频率响应特性测试系统,从实验上验证了理论计算的正确性。结果表明,该方法测量误差小于1.5%,满足环形激光器反射镜相位延迟差测量要求。
The theoretical formula between the reflection phase retardation difference of S polarized beam and P polarized in square ring resonator and the beat frequency driving voltage difference in the piezoelectric ceramic （PZT） was derived. The frequency response characteristic of S polarized beam and P polarized beam in the square ring resonator was analyzed, and a new method for measuring the phase retardation difference by measuring the voltage difference was proposed. The passive ring re- sonator frequency response measuring system was set up, and the validity of the theoretical analysis was verified by experiment. The results indicate that the measuring error is less than 1.5 %, which satisfies the requirement for the reflection phase retardation measurement.
