摘要
为适应人眼安全激光主动探测应用对探测激光高功率、窄脉宽的要求,提出了一种利用等效电路模型分析提高1550 nm脉冲半导体激光发射模块性能的方法.基于特定激光器参数建立对应的等效电路模型,并将模型引入发射模块脉冲驱动电路,通过仿真分析,得出影响模块高功率、窄脉冲激光输出特性的关键因素.将优化后两种封装的激光器接入设计制作的脉冲激光发射模块进行输出激光脉冲测试,实测结果验证了仿真的准确性,说明等效电路分析方法可应用于评价及优化提高激光发射模块的性能.最终获得了最大输出功率20 W以上、脉冲宽度小于10 ns的光脉冲,该模块实现了高功率、窄脉冲的激光输出.
Abstract
To adapt the requirements of high power and narrow pulse width of detection laser in the active detection application for the eye-safe laser,a method for improving the performance of 1550 nm pulse laser diode transmitter module using equivalent circuit model analysis is proposed.The equivalent circuit model is established based on the specific laser parameters,and the model is introduced into the pulse drive circuit of the transmitter module.The key factors affecting the output characteristics of high power,narrow pulse laser are obtained through simulation analysis.The optimized two package lasers are connected to the pulse laser transmitter module to test the output laser pulse.The measured results are consistent with the simulation results,it is proved that the equivalent circuit analysis method can be used to evaluate and optimize the performance of the laser transmitter module.Finally,the optical pulse with the maximum output power over 20 W and the pulse width less than 10 ns is obtained that realizing laser output with high power and narrow pulse.
