讨论了光谱吸收法瓦斯检测系统中半导体激光器温度控制的必要性,提出了一种基于ADN8830的高性能高稳定性半导体激光器温度控制电路的设计方案,能够实时监控激光器的温度,以稳定激光器的输出功率和波长.与传统的分立元件设计方法相比,大大简化了电路设计.实验结果表明,该温控电路具有良好的性能,激光器的温度控制精度达到±0.02℃.“,”In this paper, it is discussed that the essentiality of the laser diode temperature controller in the spectroscopy detection system of gas. A laser diode temperature controller consisting of ADN8830 is presented, in order to real-time monitoring and control of laser temperature, and to make the output power and wavelength stable of the laser diode. The ADN8830 is a highly integrated and efficient thermoelectric cooler (TEC) element. Compared to the discrete components of the traditional design methods, the circuit design is greatly simplified. The experiment result shows that the controller system high accuracy and stability in controlling temperature and the control accuracy has been achieved to be ±0.02℃.
