激光光源的稳恒控制分析与设计

Analysis and Design of Drive and Control System of Laser Source

本文设计了一种激光光源系统,其能为半导体激光器提供高稳定度的驱动电流,恒温控制(ATC)和自动光功率控制(APC),提高了半导体激光器的使用寿命和输出波长的单一性.并给出了驱动电流的稳定度实验测量.

This paper designs a kind of laser source system,which can supply high stable output current,automatic temperature control(ATC),and automatic power control(APC).With this system we can improve the life time and the pure spectrum of laser diodes. We also give an experiment measurement of output current stability.
