Abstract

By using both tungsten disulfide saturable absorber (WS₂-SA) and YVO₄/Nd:YVO₄(0.3 at.%)/YVO₄ crystal, a passively Q-switched laser centered at 1342.2 nm is first reported. Stable Q-switched pulses can be obtained. At the pump power of 12 W, a shortest pulse width of 550 ns and a pulse repetition rate of 97 kHz can be observed by a digital oscilloscope, corresponding to maximum pulse energy of 5.55 μJ and pulse peak power of 10.1 W. The results promote the promising applications of WS₂-SA in all-solid-state laser at 1.3 μm.
