摘　　要：分析了半导体激光器的激励源系统和温控系统的设计原理,关于激励源,详细介绍了恒流源和软启动电路;在温控系统中,提出了采用恒流源来设定温度限的设计思想,最后分析了系统的试验结果。The paper interpreted the design principle about excited source system and temperature - control system of laser diode. Constant-current circuit and soft-start circuit are explained detailedly in the section of excited source system and the design idea that temperature limits are set by the constant -current source is brought up in the section of temperature-control system. Finally experimental result is analysed.
