摘要
使用琼斯矩阵光学,理论分析Z型正交波罗棱镜腔运转特性。在不同波罗棱镜折射率情况下,分析波片方位角与偏振透过率、反射臂的有效反射率、输出臂的耦合反射率以及补偿波罗棱镜相位延迟的波片数关系。使用四阶龙库塔法则结合速率方程,理论分析耦合反射率的改变对调Q脉冲能量和宽度的影响。
The operational characteristics of Z-shaped orthogonal porroprism resonator are theoretical analyzed using Jones matrix optics. The relationship between azimuth angle of waveplate and polarizer transmission, effective reflectivity in feedback arm, coupling reflectivity in output arm, waveplate number which compensates the phase shift introduced by Porto prism is studied. The analysis is done with several different refractive indices of Porro prism. Using rate equation and fourthorder Runge Kutta method, the influence of output arm＇s coupling reflectivity on the output energy and pulse width of the Qswitched laser is theoretically analyzed.
