本文以连续波一氧化碳(CW-CO)激光器为对象,完成了控制线路的设计与组装。通过TRS80与M5206的数据通信对激光信号、光声信号进行采样,并组成数据文件,同时开发了若干数据处理程序。经调节谐振腔反射镜的偏移来实现激光谱线的搜索和优化。这些功能的实现为开展高精度自动光谱分析奠定了基础。 In this paper, continuous wave carbon monoxide (CW-CO) laser as the object, completed the control circuit design and assembly. Through the data communication between TRS80 and M5206, the laser signal and photoacoustic signal are sampled, and the data files are composed. At the same time, several data processing programs are developed. By adjusting the offset of the resonator mirror to achieve the search and optimization of the laser spectrum. The realization of these functions lays the foundation for high-precision automatic spectral analysis.
