【 摘 要 】

Using a new MoS2-based nanosheets as a saturable absorber (SA), a passively Q-switched (PQS) Tm, Ho:YAP laser at 2000.4 nm was proved in the paper. Under PQS mode, an average output power of over 3 W and per pulse energy of over 23 μJ were obtained in the experiment. Also, the beam quality factors were less than 1.1 in PQS mode.
