利用激光速率方程理论，对Tm，Ho激光系统计算预测得出最佳耦合输出透过率和调Q激光脉冲宽度。实验采用Tm，Ho：LuLF为增益介质，三向侧面泵浦，环形腔声光调Q。选用透过率20%和30%的输出镜作对比。在透过率20%耦合输出时，得到调Q激光脉冲能量最大为58.0 mJ，对应光光转换效率为1.45%；在透过率30%耦合输出时，得到调Q激光脉冲能量最大为62.9 mJ，对应光光转换效率1.57%，并且获得了最大动静比48.7%。激光脉冲宽度在注入能量3.25 J时为417.2 ns。与理论计算结果较为一致。

In the Tm, Ho laser system, the optimum transmittance and pulse duration was practiced using the rate equations theory. In a 2 m ring resonator, the Tm, Ho: LuLF laser material was side-pumped from three directions and Q -swtiched of acoustic -optic device. The output coupler of 20% and 30%transmittance was compared. In the 20% transmittance coupler, it was demonstrated that the Q-switched laser pulse energy of 58.0 mJ with an optical to optical efficiency of 1.45%. The 62.9 mJ energy was obtained with the optical to optical efficiency of 1.57%in the 30% transmittance coupler. And the 48.7% of dynamic to static ratio was obtained in the same injection. The pulse duration was 417.2 ns when 3.25 J energy was injected. The experiment values are in consistent with the simulation results.
