| 摘 要： | 根据通信用光纤激光器泵浦源的要求,结合半导体激光器的特性,设计了一款高性能、低成本的激光器驱动电路(包括恒流电路、控制电路和保护电路)。恒流电路采用达林顿管作为调整管,利用集成运放的深度负反馈实现恒流输出。经实验验证,本设计系统恒流源稳定度达0.03%,纹波较小,可实现对光纤激光器泵浦源激光二极管(LD)的驱动。

| Abstract: | According to the demand of fiber laser pumping source for communication, and combining the characteristics of Laser Diode, a driving circuit with high performance and low cost is designed, which is composed of constant current circuit, control circuit and protection circuit. The constant current circuit uses a Darlington transistor as an adjuster, and the deep negative feedback state of integrated operational amplifier to realize constant current output. The experiment results prove that the system has the current stability of 0.03% with small ripple,and can realize the driving of LD for pumping fiber laser. |
