Performance of LD pumped Nd:GdVO4 laser

An LD pumped high power Nd:GdVO4 laser was reported. A continuous and pulse output of 1 064 nm was obtained. In the experiment of continuous output, when the pumped power was 20.2 W, an output power of 11.5 W with a maximum optical conversion efficiency of 55.0% and a slope efficiency of 59.1% was obtained. In the acousto-optic Q-switch experiment, when the repetition is 10 kHz, a pulse width of 6.5 ns, a peak power of 52.3 kW and an energy of 340 μJ were obtained. As the repetition was 30 kHz and the minimum pulse width was 14.5 ns, the average output power was 5.18 W.
