Abstract

We present the experimental results on the laser characteristics of diode-pumped passively Q-switched Tm,Ho:GdVO⁴ and Tm,Ho:YVO⁴ lasers with a Cr2+:ZnS saturable absorber emitting in the 2-μm range. The Tm,Ho:GdVO⁴ laser exhibits better performance than the Tm,Ho:YVO⁴ laser. The minimum pulse duration of 32.7 ns is obtained with the pulse energy of 0.30 mJ, corresponding to the peak power of 9.1 kW. The slope efficiencies of continuous wave and passively Q-switched Tm,Ho:GdVO⁴ lasers are 49.9% and 36.5%, corresponding to the Q-switching efficiency of 70.2%.
