摘　　要：介绍了一种半导体激光器驱动系统,主要包括温度稳定控制电路、电流稳定控制电路和保护电路,给出了具体的参考电路。通过同时对激光器的工作电流及其温度进行精密控制,使得激光器能稳定工作。保护电路能在激光器工作过程中对其进行充分保护,防止激光器因误操作或其它因素发生损坏。实验表明,该驱动控制的激光器在恒温（室温）下工作80 min输出波长漂移不超过0.6 pm。外界环境温度10℃~50℃范围内,激光器输出波长漂移不超过16 pm。适用于对激光器稳定要求高的场合。A laser diode （LD） driving system was presented, which mainly contains high-stable temperature control circuit, high-stable current control circuit and protection circuit. Concrete circuit was given. The laser can work stably by simultaneously control the current and temperature precisely. The protection circuit can provide sufficient protection to LD during its working. Without it, LD can be easily damaged by false operation or other reasons. Experimental results show that the output wavelength of the LD under constant temperature （room temperature） drifts no more than 0.6 pm. When the environmental temperature changes from 10℃ to 50℃, the drift is no more than 16 pm, which, accordingly, can be applied to circumstances that request for high stability of LD.
