摘要：
A passively Q-switched (PQS) Tm:YAP laser was faultlessly realized with the WSe2 nanosheets as the saturable absorber (SA). A 0.97-W average output power at 1987.5 nm and a 459.0-ns pulse duration were obtained with a 9.5% optical conversion efficiency, and a 11.2-mu J pulse energy and a 24.4-W peak power were gained with a 10.2-W pump power. In addition, the beam quality factors of M-x(2) =1.11 and M-y(2) =1.16 were obtained from Tm:YAP laser in continuous wave (CW) with the output power of 2W.
