轴快流CO2激光器循环工作气体参数控制系统设计

本文介绍了一种适用于CO2激光器的气体循环控制系统。该系统所采用的可编程序控制方法和系统结构不仅能够精确地控制激光器的工作气压,而且可以根据激光器不同的工作状态和功率输出,选择不同的混合气分比和换气量。系统所有的参数不仅可以预先设定,也可在激光器运行中方便地进行改变。

Fast axial flow CO_2 laser fluit recycle control system

A CO_2 laser fluid recycle control system is described in this paper. The used structrure and programmable control means in this system permit not only the accurate control and maintenance of gas pressure substantially constant in CO_2 laser but also the automatically adjustment of the fluid ex-change volume and the different compositions of supplied mixed fluid according to the laser working sta-tus(CW or Pulse)and its output power.All parameters can be preset before the operation of the laser and can be conveniently,precisely and selectively varied at any time of the operation.
