Abstract

We demonstrate experimentally a passive Q-switched (PQS) operation of 2 μm c-cut Tm,Ho:LuVO4 laser with a WSe2 saturable absorber (SA) mirror. We obtain an average output power of 500 mW with a pulse width of 3.5 μs at 116.6 kHz and a pump power of 13.03 W. We measure the output wavelengths of the Tm,Ho:LuVO4 laser to be 2,075.8 nm at the continuous-wave (CW) mode operation and 2,056.9 nm at the PQS mode operation. The beam quality factors \( {M}_x^2 \) = 1.11 and \( {M}_y^2 \) = 1.06 are obtained in the PQS Tm,Ho:LuVO4 laser.
