摘要/Abstract

摘要： 当YSGG、GGG、GSGG、YAG、YLF作为基质材料时，Er3+的4I11/2 能级和4I13/2 能级之间能够跃迁产生2.7~3μm的激光，该波段激光在医疗、军事等方面有着重要的应用价值。在790nm泵浦光作用下，Er:YSGG作为工作物质可产生2.79μm激光。通过构建Er:YSGG能级跃迁的速率方程，对转镜调Q激光器的系统特性进行了理论分析，并在此基础上进行数值模拟，得出了在给定激光工作物质参数的情况下，系统的各个变量对转镜调Q激光器性能的影响。这些结论将为类似实验的设计和改进提供理论指导。

Abstract: 2.7-3μm laser, which has the important value of medical and military applications, are obtained from the transition 4I11/2 →4I13/2 with rare earth Er3+ as the active ions and YSGG, GGG, GSGG, YAG, YLF as the matrix material. Under the effect of 790nm pump light, the Er:YSGG as laser material can produce 2.79μm stimulated emission. By building the rate equation of Er:YSGG energy level transition, we analyze the system characteristics of rotating mirror Q-switched laser and do some numerical simulations. Result of the numerical simulations can help us obtain the the influence of system variables on the performance of rotating mirror Q-switched laser. These conclusion will provide theoretical guidance for the design and improvement of similar experiment.

Key words: laser techniques; numerical simulations; rate equation; rotating mirror Q-switched
