射频CO_2激光器实用功率控制器的设计

Practical power controller design for RF excited CO_2 lasers

随着工业技术的现代化 ,对CO2 激光器的整体性能和技术参数方面都提出了越来越苛刻的要求 ,如寿命 ,机械性能和光束质量等 .这就要求激光器使用前要确保其性能的可靠性 ,其中激光器的开关次数和连续工作时间是影响其性能的关键因素 ,本文主要介绍一种测试激光器性能用的功率控制器 ,它不仅具有通常功率控制器的功能 ,还带有自动开关功能 。

Along with the technical modernization of industry,requests towards the whole function and technique parameter of CO 2 laser become more and more rigorous,such as the lifetime,and the beam quantity etc.The reliability of the lasers must be ensured;the key factors are the switching time and the free running time,and it is important to test them.This paper presents a new laser output power controller,which can be used to test the function of lasers.It not only has the function of the normal power controller,but also can provide the function to automatically turn on and off the lasers.This new controller is simple in principle,but is practical.
