摘要：

A 2 mu m passively Q-switched Tm:YAP solid-state laser with MoS2 as saturated absorber was demonstrated in this work. MoS2 two-dimensional materials were prepared by using the method of chemical vapor deposition. The laser achieved high peak power of 21.2 W and high single pulse energy of 19.5 mu J, while maintaining a short pulse width of 916 ns. This is the first time that the peak power of a Tm:TAP solid-state laser based on a MoS2 saturated absorber has reached 21.2 W. The beam quality factor was M-x(2) = 1.08 and M-y(2) = 1.10.
