| Abstract: | An acousto-optic Q-switched, LD pumped,quasi-continuous Nd∶GdVO4 laser at 1.06 μm is reported. At the pump power of 4.15 W and the repetition rate of 40 kHz, the maximum average output power 1.46 W is obtained, corresponding to an optical conversion efficiency of 35.1% and a slope efficiency of 44.2%. At the repetition rate of 10 kHz, the shortest pulse width 24 ns and the highest single pulse energy 63.2 μJ are produced, corresponding to the peak power of 2.62 kW. |
