大功率高亮度固体激光腔的选择
Selection of resonator of high power and high brightness solid state laser
-
摘要: 分析了大功率激光器可供选择的几种腔型的动力稳定区。并对最近报道的两种固体激光腔型进行了评价，指出了存在的问题，提出采用小曲率半径的凹面镜和一凸面镜构成谐振腔是设计大功率高亮度固体激光器的较好方案。Abstract: The dynamic stable regions of several kind of resonator, which can be used in high power laser, have been analyzed. Two kind of solid state laser resonator reported recently have been evaluated, and problems in those resonator have been pointed out. The best design for high power and high brightness solid state laser has been put forward: the best resonator is composed of a short radius concave mirror and a convex mirror.
