High-energy side-pumped laser can be applied in the field of laser cosmetic surgery, laser making and long distance detection. By utilizing side-pumped technology and electro-optic Q-switching technology,high-repetition-rate and narrow-pulse-width laser centered at 1 064 nm wavelength could be obtained. The intensity distribution of the laser output could be uniformed by making use of diffractive optical elements . Under the condition of 700 V input voltage and 10 Hz driving Q-switching frequency,426 mJ,1 064 nm laser pulses were obtained . The experiment results show that the combination of side-pumped technology and diffractive element uniformation technology could lead to the achievement of high-energy and uniform intensity distribution laser output.
