摘要：
A passively Q-switched (PQS) operation of Tm,Ho:LuVO4 laser is experimentally demonstrated with a graphene saturable absorber (SA) mirror. An average output power of 1034 mW at 54.5 kHz is acquired with an 8% optical-optical conversion efficiency. The energy per pulse of 40.4 J and a peak power of 56.07 W are achieved; the narrowest pulse width of 300 ns is acquired, and the output wavelengths of Tm,Ho:LuVO4 are 2075.02 nm in a continuous wave (CW) regime and 2057.03 nm in a PQS regime.
