摘　　要：设计了一款基于Marx Bank脉冲发生原理的纳秒脉冲激光驱动器。该驱动器电路由两级电路组成,一级为触发脉冲产生电路,一级为纳秒脉冲生成电路。通过装机、调试,测得所得驱动器的最大峰值电流为12.5 A,半高全宽为1.51 ns,重复频率为100 kHz,满足了大幅度纳秒脉冲半导体激光器驱动器的设计要求。One nanosecond pulse driver based on Marx Bank circuit is designed for driving laser diode perfectly. This drivig circuit includs two groups： one offers the trigger pulse and the other one generates the nanosecond pulse. The measurment results of the nanosecond pulse are as follows： the full width at half maximum is 1. 51 ns, the peak current value is 12.5 A and the repetition frequency is 100 kHz. It is suitable for obtaining shorter optic pulse of the laser diode.
