A laser diode side-pumped electro-optical Q-switched Nd:YAG green light laser with high repetition rates, short pulse width, and high peak power was demonstrated. We studied the performance of the oscillator at the repetition rates from 100 to 500 Hz. At 500 Hz, 61 mJ, 5 ns of 1064 nm infrared light pulses were obtained with an oscillator-amplifier system. The peak power of the pulse was 12 MW. By frequency doubling with a LiB(3)O(5)(LBO) crystal, 32.5 mJ, 4.6 ns of 532 nm green light was achieved, corresponding to a peak power of 7 MW. The frequency conversion efficiency was 53.3%.
