摘要
Ho：YAG晶体因其优良的机械性能及光谱特性，成为高重频2μm激光器的首选晶体。为获得高效率、高功率的高重频2μmHo：YAG激光器，分析了Ho：YAG晶体的物化参数、光谱特性以及单掺Ho^3＋激光器的发光机理，接着从速率方程出发建立了高重频准连续Ho：YAG激光器转换效率的计算模型，利用该模型分析了输出镜透过率、激光模式大小、泵浦一激光模式比和晶体掺杂浓度等参数对高重频准连续Ho：YAG激光器转换效率的影响，并提出了参数设计范围。
Ho ： YAG crystal has become the top choice of high-repetition-frequency 2μm laser because of its good mechanical properties and spectrum characteristics. In order to acquire high efficiency and high power of highrepetition - frequency 2μm Ho- YAG laser, physicochemical parameters, spectrum characteristics of Ho.. YAG crystal and radiation mechanism of singly-doped Ho^3 ＋ laser are analyzed in this paper, and then calculation model of conversion efficiency of high-repetition-frequency Ho ： YAG laser is developed via rate equation. The parameter effect of output coupler transmittance, laser mode size, the ratio of pump-laser mode and Ho-doping concen- tration on conversion efficiency of high-repetition-frequency Ho：YAG laser is analyzed using this calculation model, and the design scope of those parameters is put forward.
