摘要: 在考虑基态重吸收的前提下，建立了准三能级Tm:YAP自调Q激光器的速率方程理论模型。通过数值模拟，确定了Tm:YAP的晶体掺杂浓度为5.0at.%，长度为5 mm，输出透过率为6%的耦合镜，为实现稳定的自调Q脉冲输出可行性提供了理论依据。讨论了泵浦功率在7~18 W时，脉冲宽度、重复频率、峰值功率、脉冲能量等随泵浦功率的变化关系。在泵浦功率为18 W时，脉冲宽度为5.1 μs，重复频率为22.7 kHz，峰值功率为12.1 W，脉冲能量为61.9 μJ。
Abstract: Under considering the reabsorption of ground state, the quasi-three-level rate equation theoretical model of Tm:YAP self-Q-switching solid-state laser was established, and the crystal doping concentration of 5.0 at.%, the length of 5 mm and the coupling mirror with transmission rate of 6% was determined by numerical simulation, which provided a theoretical basis for the realization of stable self-Q-switching pulse output. The pulse width, repetition frequency, peak power and pulse energy as functions of pump power at 7 - 18 W were discussed. The pulse width is 5.1 μs, the repetition frequency is 22.7 kHz, the peak power is 12.1 W and the pulse energy is 61.9 μJ.
