Abstract

The coupling of optical energy from a lamp into a laser rod using a spherical mirror enclosure has been analyzed using geometrical optics. The calculations indicate that about 75% coupling can be obtained for typical sized laser rods and spheres. Experimental results for a 3 mm x 30 mm Nd: Cr: YAG rod are given. Using external resonators, a slope efficiency of 1.15% and an output power of 3.4 W were observed for an input power of 870 W.

摘要

利用几何光学对使用球面镜外壳将灯的光能耦合到激光棒中的情况进行了分析。计算表明，对于典型尺寸的激光棒和球体，可实现约75%的耦合。给出了一根3毫米×30毫米钕铬钇铝石榴石（Nd:Cr:YAG）棒的实验结果。使用外部谐振器时，在输入功率为870瓦的情况下，观察到斜率效率为1.15%，输出功率为3.4瓦。
