摘　　要：DFB可调谐二极管激光器是激光光谱测量系统中的最主要部件之一,它的输出波长与辐射功率的稳定性决定测量系统的稳定性。影响DFB可调谐二极管激光器输出波长和输出功率的因素主要为激光器的注入电流和工作温度,而工作温度对输出特性的影响更大。设计了激光器温度控制电路,并实验分析了PI参数对温度控制稳定性的影响以及温度控制的短期稳定性;将设计电路应用在DFB可调谐二极管激光器上进行激光器输出波长与输出功率的长期监测,得到激光器输出波长的标准偏差为0.2×10^(-6),输出功率的标准偏差为0.02mW。The DFB tunable diode Laser is one of the most important components in the laser spectrum measurement system. The main factors that affect the output wavelength and output power of DFB tunable diode laser are the injection current and operating temperature, and the latter has a bigger effect on the laser. This paper designed temperature control circuit for laser, and analyzed the influence of PI parameters on the temperature control stabilization and short term stability experimentally; the designed temperature control circuit is applied on DFB tunable diode laser for study of long-term monitoring in laser output wavelength and output power, and achieved that standard deviation of the laser output wavelength is 0.2 × 10-6 , the standard deviation of output power is 0.02 mW.
