| 摘 要： | 为了使半导体激光器的激光波长和输出功率稳定，必须对其温度进行控制。介绍了LD泵浦固体激光器恒温控制系统的软、硬件方面设计。温度采集电路采用具有高输入阻抗和高共模抑制比的测量放大电路，利用半导体制冷器（thermo electric cooler，TEC）作为控温系统的控温执行器件。由改变驱动TEC电流的方向来实现制冷或者加热，软件采用增量型防积分饱和的数字PID算法，根据实验结果温控控制精度在土0．5℃，可以满足对半导体激光器温度控制精度和稳定性的要求。

| Abstract: | In order to make wavelength and power stabilization,it is necessary to control temperature as high precision. This paper presents the software and hardware design of constant temperature control unit of LD-pumped solid laser. Temperature sample circuit adopts the measurement amplification circuit with high-input impedance and high CMRR.It uses TEC as temperature-control operating unit of the system.To control the temperature,we change the direction of TEC drive-current Software adopts the incriment anti-int... |
