| 摘 要： | 温度是影响半导体激光器（LD）寿命和输出特性的重要因素之一。为保证LD输出稳定的激光模式和功率，采用以ADC和DAC集成的微处理器芯片C8051F350和具有双极性输出电流的TEC驱动芯片MAX1968为控制核心，以积分分离和变速积分增量式相结合的数字PID算法为运算程序的自动温度控制系统(ATC)控制TEC驱动电流的方向和大小，实现对LD的加热或制冷，使其工作在恒定温度。实验证明，应用该系统，LD在0℃～40℃环境温度范围内能很快稳定在设定温度，且其不确定度为±0.03℃。

| Abstract: | The temperature is important for the properties of laser diode (LD). For increasing lifetime of LD and obtaining steady laser output, the automatic temperature control system to control the current of the thermo electric cooler (TEC) is applied. The temperature control system consists of C8051F350 which integrated with ADC and DAC and MAX1968 with two-way current output. It uses the enhanced digital PID algorithm combining integral separating and shift integration incremental algorithm to achieve the two-way control of the temperature of LD. The result shows that the temperature of laser can reach the value preset rapidly and stably with stability of ±0.03℃ while LD working in range from 0℃～40℃. |
