Abstract
An acousto-optic Q-switched Tm:GdScO3 slab laser at different pulse repetition frequencies was successfully demonstrated for the first time. The size of a slab crystal doped with a 2 at% Tm3+ is 2 mm × 4 mm × 20 mm. With the pump power of 33 W, a maximum average output power of 3.03 W was obtained with center wavelength of 1980 nm at pulse repetition frequency of 20 kHz. The optical-to-optical conversion efficiency and slope efficiency were 9.18% and 16.66%, respectively. The maximum pulse energy was 0.60 mJ with pulse width of 160 ns at 1 kHz, corresponding to the peak power of 3.75 kW. In addition, at the pump power of 33 W, the beam quality factors M2 for horizontal and vertical directions were 1.33 and 1.08, respectively.
