随着高功率TEA CO2激光器技术的快速发展, 及其在工业加工、科学研究、航空航天等领域的广泛应用, 对其自身控制系统也提出了更高的性能要求。针对所研制的高功率TEA CO2激光器, 设计了一种基于DSP数字信号处理器技术的控制系统, 分别从硬件、软件两方面对控制系统的核心单元做了详细的介绍; 为了克服激光器在工作过程中产生的强电磁干扰, 对控制系统采取了屏蔽箱体结构、电源滤波、安全接地、数字滤波、关键数据存储自恢复、抗复位干扰等设计。经过激光器长时间运行试验, 控制系统工作稳定、可靠, 控制响应速度快, 同时满足了抗强电磁干扰的设计要求, 具有很好的实用和推广价值。

As the rapid development of high-power TEA CO2 laser technology and its extensive application on industrial production, scientific research, aeronautics and astronautics and other fields, higher performance demand on control system for high-power TEA CO2 laser was put forward. A control system based on Digital Signal Processor(DSP) was designed for the high-power TEA CO2 laser, and the core module was introduced on hardware and software in detail. To overcome the severe electromagnetic interference generated during the working process of laser, shielding enclosure, power filter, safety ground, digital filter, storage and recovery of critical data, resisting reset interference and other designs were taken measure on the control system. After long term run-time test on the high-power TEA CO2 laser, the control system works stably and firmly, controlling and responding quickly, meanwhile satisfying the design request of resisting strong electromagnetic interference, with good application and popularization value.
