Abstract

Abstract A passively Q-switched (PQS) Er:YAP laser at ∼3 μ m with the two-dimensional saturable absorber (SA) tin diselenide (SnSe 2 ) nanosheet as SA was successfully demonstrated for the first time. Under the maximum absorbed pump power of 4.0 W, the obtained continuous-wave maximum output power of Er:YAP laser was 258 mW with a corresponding slop efficiency of 7.18%. In the PQS experiment, laser pulses with the shortest pulse duration of 198 ns were yielded with a repetition rate of 317 kHz under the maximum absorbed pump power of 4.0 W, and the corresponding single pulse energy and pulse peak power were 0.66 µ J and 3.3 W, respectively. The investigation indicates that SnSe 2 has the potential to be an outstanding laser modulator for PQS solid-state laser at 3 μ m wavelength.

二维二硒化锡作为被动调q Er:YAP 3 μm固体激光器的可饱和吸收体

首次成功地展示了以二维饱和吸收剂(SA)二硒化锡(SnSe 2)纳米片作为SA的被动调q (PQS) Er:YAP激光器。在最大吸收泵浦功率为4.0 W时，得到的Er:YAP激光器连续波最大输出功率为258 mW，相应的斜率效率为7.18%。在PQS实验中，在最大吸收泵浦功率为4.0 W的条件下，以317 kHz的重复频率产生了最短脉冲持续时间为198 ns的激光脉冲，对应的单脉冲能量和脉冲峰值功率分别为0.66µJ和3.3 W。研究表明，snse2有潜力成为3 μ m波长PQS固态激光器的优秀激光调制器。
