摘　　要：报道了全固态激光器连续抽运高重复率电光调QNd∶YVO4激光器的实验和理论分析结果,用BBO晶体作电光调Q元件,在激光二极管(LD)端面抽运Nd∶YVO4激光器中实现了较高重复率的电光调Q输出.实验中在1kHz重复率下,抽运功率为10W时,平均功率超过170mW.对输出功率曲线中的凹陷现象进行了分析,指出了制约激光器的内在诸因素,并用传播圆-变换圆图解分析方法给出了合理的解释.A laser diode（LD）continuous-wave（CW）end-pumping high repetition rate electro-optic（EO）Q-switching Nd∶YVO4 laser was experimentally and theoretically studied.In experiments,using BBO single crystal as an EO Q-switch,with 10 W pump power,about 170 mW average power was obtained at 1 kHz repetition rate.The dips in the output power curves were analyzed,A reasonable explaination was given and a way of improving the output was pointed out through the graphic analysis of the transmitting and transforming circle.
