The passively Q-switched (PQS) operation of a Tm:YAP laser was experimentally demonstrated with an MoSe₂ saturable absorber (SA). In the PQS mode, an average output power of 1.084/1.744 W with a pulse width of 686.0/1222 ns at 196.5/177.7 kHz was acquired from Tm:YAP laser under an output couple (OC) with transmittances T of 2%/5%, corresponding to an optical–optical conversion efficiency and an output wavelength of 7.2%/12.7% at 1989.2/1986.6 nm. In addition, the beam quality factors of the PQS Tm:YAP laser in the X and Y directions were less than 1.15.

具有MoSe 2饱和吸收剂的Tm：YAP激光器的无源Q转换操作

用MoSe ₂饱和吸收体（SA）实验证明了Tm：YAP激光器的被动调Q（PQS）操作。在PQS模式下，从Tm：YAP激光器在输出对（OC）下以2％/ 5的透射率T获得了平均输出功率1.084 / 1.744 W（在196.5 / 177.7 kHz时的脉冲宽度为686.0 / 1222 ns）％，对应于光-光转换效率，在1989.2 / 1986.6 nm处的输出波长为7.2％/ 12.7％。另外，PQS Tm：YAP激光器在X和Y方向上的光束质量因子小于1.15。
