摘　　要：从速率方程出发,建立了激光二极管(LD)脉冲泵浦的增益开关型Nd:YVO4微片激光器的数学模型。通过数值求解,得到了输出脉冲宽度和脉冲建立时间随泵浦速率的增加而减小,输出脉冲个数随泵浦速率的增加呈非线性单调递增关系,理论计算与实验研究结果基本符合。在实验中,当泵浦脉宽为40μs,泵浦电流为22.4A时,获得了脉宽为22ns的脉冲输出。By numerically solving the rate equation,we found,the pulse width and buildup time of the output pulses decreased as the pumping rate increased;the number of the output pulses increase as the pumping rate increase.And the theoretical and experimental results agree well.In the experiment,the output laser pulse width of 22ns is obtained when the width of pumping pulse is 40μs and pumping current is 22.4A.
