摘要

提出了一种基于SnSe2饱和吸收体的2 μm Tm: YAP被动调q固体激光器。随着泵浦功率的增加，激光输出功率达到430 mW，最短脉冲宽度为810.7 ns，最大重复频率为59.55 kHz，单脉冲能量为7.22 μJ，峰值功率为8.9 W。在最大输出功率下，成功测量到光束质量因子M2x为1.43。这是第一次在使用Tm: YAP晶体和SnSe2作为饱和吸收剂的固态激光器中实现810.7 ns的脉冲宽度。

Short-Pulse Mid-Infrared Laser Based on SnSe2 Saturable Absorber

We propose a 2 μm Tm: YAP passively Q-switched solid-state laser based on SnSe₂ saturable absorber. With increase in the pump power, the output power of the laser can reach 430 mW corresponding to a shortest pulse width of 810.7 ns, a maximum repetition frequency of 59.55 kHz, a single pulse energy of 7.22 μJ, and a peak power of 8.9 W. The beam quality factor M²_x is measured successfully to be 1.43 under the maximum output power. This is the first time that a pulse width of 810.7 ns is achieved in a solid-state laser, using a Tm: YAP crystal and SnSe₂ as the saturation absorber.
