摘要
采用矩阵光学理论和实验相结合的方法 ,分析了输出镜对双棒串接固体激光器输出光束的影响。结果表明 ,输出镜的位置影响了双棒串接固体激光器稳定范围和模体积 ,进而影响其输出功率 ,等间距放置的谐振腔模体积相对较大 ,在输入功率相同时 ,其输出功率也相对较大。输出镜的位置也影响了输出光束的光斑半径w0 和远场发散角θ0 ,二者随输出镜与棒主平面距离的变化关系是相反的。
Influence of position of output mirror on beam of two rod solid state laser has been analysed by means of matrix optics and experiment. The results show that the stability zone,the mode volume and the output power of two rod solid state laser are affected by the position of output mirror. The mode volume and output power of equal interval resontor are larger than the other resontors.The facula radius w 0 and the far field divergent angle θ 0 are also affected by the position of the output mirror.The optimum transmissivity of output mirror for two rod solid state laser has been investigated by experiment.
