摘　　要：温度对于外腔半导体激光器的特性有很大的影响,对其温度进行高精度的控制,是保证外腔半导体激光器输出波长稳定的关键技术之一。本文介绍了外腔半导体激光器的高精度温度控制原理和方法,提出了采用PID控制原理的模拟电路设计和以单片机为核心的数字电路设计相结合的双稳温度控制方案,并对其进行了理论分析和实验研究。The temperature greatly influences the characteristics of external cavity laser diode （ ECLD）. The high accurate temperature control of ECLD is one of the key technologies of stable output wavelength. The principle and method for high accurate temperature control of ECLD are described in this paper, The scheme of dual temperature control is given, which is combined by the analog circuit with DID control theory and the digital circuit design based on micro controller,and it is studied and analyzod.
