Abstract

We report a cw Tm:YAP laser resonantly pumped Ho:LuVO4 laser in passively Q-switched (PQS) mode with Cr2+:ZnS as a saturable absorber (SA). The influence of different transmittances of the output coupler on laser output performance is analyzed. With T = 50%, the maximum PQS average output power of 2.3W is obtained, corresponding to the slope efficiency and the opticaloptical conversion efficiency are 35.1% and 19.8%, respectively. Also, the minimum pulse width of 100 ns is achieved at the maximum pulse repetition frequency of 34.2 kHz. When the maximum cw output power is 2.7 W, the beam quality factor of the horizontal direction M_x² = 1.04 and the vertical direction M_y² = 1.10 are obtained. In addition, the central wavelength of the laser output remains to be 2057.5nm with the output coupler transmittances of 50% and 60% in both cw and PQS operations. The results show that the Cr²⁺:ZnS can be used as an SA in a Ho:LuVO₄ laser around 2-μm wavelength.
