摘要

利用基态吸收效应，实现了高平均输出功率（Pout）自调q （SQS）掺铥的YAlO3 （Tm:YAP）板状激光器。利用端泵送板状晶体的理论模型预测了Tm:YAP中的温度和应力分布。利用三种曲率的输入反射镜获得了稳定的SQS脉冲序列。在曲率为500 mm的条件下，泵浦入射功率为66.80 W，输出功率为15.72 W，脉冲宽度为1.08 μs，斜率转换为57.1%。此外，SQS激光器的Pout是稳定的，在1小时内获得了0.45%的均方根稳定性。该激光器具有良好的光束质量因子M2 <；1.3. 据我们所知，在2 μm波段，与其他SQS激光器相比，该激光器具有最高的Pout、斜率效率和光束质量。

A 15.72-W self-Q-switched Tm:YAP slab laser

A high average output power (P_out) self-Q-switched (SQS) Tm-doped YAlO₃ (Tm:YAP) slab laser was achieved using the ground-state resorption effect. A theoretical model of the end-pumped slab crystal was used to predict the temperature and stress distributions in Tm:YAP. Stable SQS pulse trains were obtained using input mirrors of the three curvatures. Under a curvature of 500 mm, a P_out of 15.72 W and a pulse width of 1.08 μs were obtained with an incident pump power of 66.80 W, corresponding to a slope conversion of 57.1 %. In addition, the P_out of the SQS laser was stable, and a root mean square stability of 0.45 % was acquired in an hour. The laser exhibited a good beam quality factor M² < 1.3. According to our knowledge, this laser has the highest P_out, slope efficiency and beam quality compared with other SQS lasers in the 2 μm band.
