摘　　要：针对目前存在的光纤测量系统中激光光源受温度影响的问题，根据激光二极管（ＬＤ）的光输出特性，采用自动光功率控制电路（ＡＰＣ），通过合理的元件参数配置，研制了光功率稳定可调的激光光源．实验表明，在 １０—４０℃温度范围内激光光源输出的光功率稳定度达到±０．１ｄＢ，达到了标准光源的技术指标．According to the out light speciality of the Laser Diode (LD), the Auto - Power Control (APC) circuit is adopted to make the adjustable and steady light source through configuring the suitable device parameter, solving the problem that the laser light source is easily effected by the temperature among the present optical fiber testing system. The experiments show the stability of the laser diode's out light power is ±0.1dB in a large temperature range from 10℃ to 40℃ ,which reaches the standard light source's parameters.
