Abstract

In this paper, a passively Q-switched Tm:YAP laser with two-dimensional (2D) tin diselenide (SnSe₂) nanosheet prepared by chemical vapor deposition (CVD) method as SA was demonstrated for the first time. The microstructure and optical characteristics of SnSe₂ nanosheet were investigated to characterize it. Continuous-wave (CW) Tm:YAP laser was demonstrated firstly. The 6.9 W absorbed pump power was used to generate 2.36 W maximum output power with corresponding slop efficiency of 45.9%. The beam profiles and quality factor were measured, respectively. By inserting the SnSe₂ into the plano-concave resonant, a Q-switched Tm:YAP laser operation at 2 µm was realized. The Q-switched laser had a maximum average output power of 411 mW, a shortest pulse duration of 2.4 µs, a maximum pulse repetition frequency of 43.2 kHz, a maximum pulse energy of 9.51 μJ and a highest peak power of 3.96 W.
