TEC的高精度半导体激光器温控设计
|
摘要
热电制冷器(TEC)作为半导体激光器(LD)的制冷方案,具有体积小、易于控制等优点。但基于TEC的制冷方案中TEC的制冷功率和目标散热功率之间需要有良好地匹配关系,否则将会导致制冷不足或者导致功耗过大。根据LD组件热负载匹配TEC制冷功率,并通过比例-积分-微分(PID)控制方法实现温控参数的优化设计,实现了基于TEC的LD温度控制系统。经实验验证:该系统能够对LD的工作温度实现控制范围为5℃~41℃、稳态误差小、控制精度为±0.05℃的高精度、高稳定性控制,并在高精度的波长测试中得到了很好的应用。
Thermoelectric cooler(TEC) had an extensive prospect for the application of refrigeration system for laser diode(LD) for its advantage such as small in size, easy to control and so on. But it was necessary to ensure the match between the cooling power of TEC and the thermal power of the target;otherwise it would lead inadequate cooling or excessive power dissipation. In this paper, a high precision thermostat system with TEC for laser diode was designed. In this system, the cooling power of TEC was determined by the thermal load of LD, proportional-integral-derivative(PID) control method was used to optimize the parameters of the thermostat system. An experiment was executed to verify the design. The experimental results showed that the work temperature of LD could be controlled between 5℃ and 41℃with a control accuracy of ±0.05℃ and the steady state error was small. The system could be a good solution for the high-precision wavelength testing.
