| 摘 要： | 研究了在考虑晶体热效应的情况下,如何最优化设计激光二极管(LD)端面抽运的固体激光器。综合考虑抽运光束分布、抽运功率、谐振腔结构以及激光介质的热效应对激光器转换效率的影响,给出设计激光器的一套仿真计算算法。结果表明,热致衍射损耗与抽运光半径、抽运功率、腔长、振荡光半径以及晶体材料有关,与输出镜透射率以及重复频率无关。在考虑热致衍射损耗的情况下,当抽运功率一定时,最佳的抽运光参数和谐振腔参数能使Nd:YAG的转换效率最大。

| Abstract: | Under the influence of thermal effect,how to optimize the conversion efficiency of laser diode(LD) end-pumped solid-state lasers is analyzed.Considering the effect of pump beam distribution,the laser medium and the resonator structure,a simulation algorithm is designed to calculate the thermal effects and laser conversion efficiency.The results show that thermally induced loss is relevant to pump radius,pump power,cavity length,oscillation light radius and crystal materials.It is independent of output mirro... |
