Q-switch technology has become an important and irreplaceable technology in many applications.Electro-optic Q-switch technology has a lot of advantages,such as short time,high efficiency,Q-moments can be controlled accurately,the narrow pulse width (10~20ns),the high peak power,simple structure,low insertion loss,etc.The emergence of Q-switch technology has improved the practical application of laser technology greatly, particularly in pulse laser range finder,in laser radar ,in laser cosmetic and in laser processing. The topic of this article mainly experiment and study about high repetition frequency E-O Q-switch Nd: YAG solid laser system which pumped by Krypton lamp.We carried out the high repetition frequency E-O Q-switch Nd: YAG experiment with the coordination of high repetition frequency Q-switch power and the laser , analysised the characteristics of the laser output ,measured the laser set-up time and the pulse width at different frequencies and different injection power ,discussed the changes between them . At last,We acquired laser bean which frequency was 30kHz, average power was 45.96W when pump power is 6200W, the laser’s conversion efficiency of light to light was 7.413‰.
