摘　　要：温度对半导体激光器的特性有很大的影响.在要求半导体激光器输出波长稳定的情况下,必须对其温度进行高精度的控制。本文利用高信噪比的运算放大器和普通的负温度系数温度传感器及半导体致冷器做控温元件,研制了一种用于半导体激光器温度控制的高精度温控仪,控制精度可达±0.05℃.The temperature greatly influences the characteristics of laser diode. If a stable output wavelength is required, the temperature of the laser diode must be maintained a constant level. In this paper, we use the operation amplifier with high S/N, a normal temperature sensor with negative temperature modulus, and a semiconductor cooler as temperature control instrument, and we succeed in inventing a high precision temperature instrument which is used in the semiconductor diode temperature control, the precision of the controlled temperature is ±0.03℃.
