Paper Abstract

Passive Q-switching (PQS) operation of 2 μm a-cut Tm,Ho:YAP laser was experimentally demonstrated with a MoS2 /WS2 saturable absorber (SA) mirror. A MoS2 SA was used in the experiment, the PQS Tm,Ho:YAP laser was the first acquired with an average output power of 3.3 W and per pulse energy of 23.31 μJ, and the beam quality factors of Mx =1.06 and My =1.06 were measured. A WS2 SA was used in the experiment, an average output power of 696 mW and a peak power of 1.79 W were acquired from PQS Tm,Ho:YAP laser with the pump power of 9.26 W, corresponding to pulse widths of 9.1 and 5.6μs and the optical-optical conversion efficiencies of 7.5% and 4.1%. The beam quality factors of Mx =1.05 and My =1.06 were measured.
