LD-single-end-pumped A-O Q-switched Nd:GdVO₄ laser with short pulse width at high repetition rate

Laser diode pumped Q-switched solid state lasers with high repetition, short pulse width and high peak power have practical applications in laser radar, laser machining and so on. But those with higher repetition rate will be more popular in the future. The effects of pumped power and output transmission on pulse width are analyzed at die repetition rate of 10-100 kHz respectively. LD singleend-pumped A-O Q-switched Nd:GdVO₄ laser has been developed and the laser output of short pulse width at the repetition rate of 100 kHz is obtained. The results at the repetition rate of 80 kHz, pulse width of 17.7 ns, average output power of 3.49 W and peak power of 2.46 kW and at the repetition rate of 100 kHz, 19.6 ns, 3.52 W and 1.79 kW, have been obtained respectively.
