摘　　要：介绍了激光通信中用于信标探测的大功率窄脉冲半导体激光器的驱动仿真方法和测试方法,原理仿真采用储能法在multisim中进行激光器驱动功能验证,然后利用器件的IBIS或者spice模型对核心器件功能进行了电源完整性和信号完整性仿真,最后介绍了输出光脉冲的峰值功率与平均功率的测试方法。最终设计结果表明,功能仿真和后端仿真结果与驱动电路的电流和脉宽设计参数一致。The simulation method and test method of high power narrow pulse laser diode driver are introduced. The laser driver principle function is verified with Energy-storage method in multisim. Based on the theories of power integrity and signal integrity, the core device diagram is simulated with IBIS models or SPICE models of these devices. Finally, the test method of peak power and average power of output light pulse is expound. The final test results show that the functional simulation and the back-end simulation coincide with the design parameters of the current and pulse.
