小镜法准直正支共焦非稳腔
-
摘要: 介绍了小镜法准直正支共焦非稳腔的原理、方法和步骤,并将它与传统使用的几种方法进行了比较。实验分析结果表明:小镜法除兼容其它方法的优越性外,还特别适合于需要确定强激光束场焦点位置的场合。Abstract: The principle and procedure of aligning a confocal positive branch unstable resonator with small-mirror method are presented in this paper. The small-mirror method is compared with some others, experimental result and theory analysis have shown that the small-mirror method has a great part of other methods?advantages, and that it is suitable to be used when the accurate focus point position of high power laser beam in far-field should be located.
