【摘要】 采用矩阵光学方法,对适用于可见光的圆筒形增益区同轴四镜腔中的腔镜因倾斜而产生的失调特性进行了分析,给出了相关计算公式。该四镜腔由同轴的一个复曲面全反镜和两个光学玻璃加工的透镜和一个平面输出镜组成。以He-Ne激光器为例,给出了数值计算结果,关键元件复曲面镜的失调对输出的影响较大。这为腔元件的加工以及腔镜的安装调试提供了参考。更多还原

【Abstract】 Using the matrix optics methods,the misalignment characteristics of the mirrors of the coaxial four-mirror resonator with annular gain media are analyzed,and some related calculation formulas are presented.This four-mirror resonator consists of a toric mirror,two lens made of optical glass and a flat mirror.Some numerical calculation results are given by applying the resonator to a He-Ne laser,and the results show that misalignment of the key cavity element(the toric mirror)has great effects on output.更多还原
