| 摘 要： | 针对半导体激光泵浦的YAG自锁模Z型谐振腔,利用光学谐振腔的传播圆方法,在不考虑热透镜效应情况下进行理论计算和数值分析,求出了输出光斑半径和腰斑半径。并通过MATLAB作图对两种情况下的稳区进行分析,得出了腔参数对稳区的影响:克尔介质的尺寸影响较小,折叠镜的曲率半径增大可使稳区右移并增大,腔长增加使稳区左移并变小。

| Abstract: | In view of YAG self-mode-locked Z-cavity,by using propagation-circle method of optics cavity,the LD end-pump Nd was calculated and analyzed,which obtained the output facular radius and facular radius of middle without thermal lens effect.By analyzing stable area through MATLAB chart,the effects of different property of cavity on stable area of resonator can be obtained: the effect of Kerr type Medium is very small,with the growth of radius of mirror the stable area shift to right and becomes bigger,with the... |
