The active/passive Q-switching operation of a 2 mu m a-cut Tm, Ho: YAP laser was experimentally demonstrated with an acousto-optical Q-switch/MoS2 saturable absorber mirror. The active Q-switch laser was operated for the first time, to the best of our knowledge, with an average output power of 12.3W and a maximum pulse energy of 10.3 mJ. The passive Q-switch laser was also the first acquired with an average output power of 3.3 W and per pulse energy of 23.31 mu J, and the beam quality factors of M-x(2) = 1.06 and M-y(2) = 1.06 were measured at the average output power of 2 W.
