Paper Abstract

The laser diode side-pumped electro-optical Q-switced Nd:YAG laser of high single pulse output energy were studied. Two alternated semicircular LDA module was used to directly side pump the Nd:YAG crystal of a series of two-rod. Each module consists of 30 laser diode which peak power is 100W. KD*P crystals is used as the electro-optic Q switch. And the ABCD law of the Gaussian beam propagation is applied to calculate the area of the stability of the resonator cavity, and a more reasonable parameters of the resonant cavity is given. A 1064nm dynamics laser that maximum output energy of 140mJ and pulse width of 10ns is obtained at a repetition rate of 20Hz when the pump energy is 1200mJ.The optical-optical conversion efficiency is 11.7%.
