Abstract:

The paper discusses the results of numerical simulation of the processes in discharge chambers (DC) of the fast-flow CO₂ lasers. The conditions of axial glow discharge in conical- and parallelepiped-shaped DCs are under study. It is shown that the output power and efficiency of the CO₂ lasers can be increased by using conical tubes narrowed in the anode-cathode direction. For the parallelepiped-shaped DCs, two-dimensional flow in the narrow-channel approximation is considered. Two-dimensional distributions of vibrational and gas temperatures, as well as the degree of gas ionization inside DC, have been obtained.
