摘要： 半导体激光器性能受温度影响较大,为了提高其工作稳定性,设计了一个应用于半导体激光器的恒温控制系统.该系统由05 mA恒流源对Pt100温度传感器供电,采用四线制测量方法获得精确的温度信号.应用TLC2652斩波放大器设计前置放大器,并采用差分放大电路对信号进行后续比较放大.使用半导体制冷器(TEC)制冷,实现系统的恒温控制.经实验数据分析可以看出,该恒温系统可有效地工作,温度控制偏差最大为±002 ℃.通过调节相应参数,可自由设定恒温系统的温度值,应用于不同温度控制环境.

Abstract: To some degree,the performance of semiconductor lasers is influenced by temperature,in order to improve the stability of their work,this paper designed a temperature control system semiconductor lasers.The system used 0.5 mA constant current source to supply power for Pt100 temperature sensor,fourwire measurement method was used to obtain accurate temperature signal.TLC2652 chopper amplifier was applied to design preamplifier.And a differential amplifier circuit was used to subsequently compare and amplify signal.The semiconductor cooler (TEC) was applied to achieve constant temperature control of the system.After the experimental data analysis,we can see that the constant temperature system can effectively work,the maximum deviation of temperature control is ±002 ℃.By adjusting the corresponding parameters,the temperature thermostat of system can be free to set,so as to use it in different temperature control environments．
