Research and design of discharge tube structure of fast-axial-flow CO2 lasers

In order to grasp the influence of the discharge tube structure on the flow field and working performance of a high power CO2 laser and get a more uniform and stable glow discharge,numerical simulation of the flowing status in discharge tube was done and the computational results matched the experiments results well.The flow fields of different tubes were compared.A new discharge tube structure was designed.The results showed that the flowing field characteristics influenced the uniformity and stability of the glow discharge in tubes.A more uniform flow field and discharge could be got in the new tube needing more optimization.
