Paper Abstract

A quantitative investigation of the excited CO2 molecules diffusion display in industrial lasers was done. It is shown that in the diffusively cooled lasers diffusion results in an additional gain on the tube axis which depends on the gas mixture contents and pressure, beam sizes, and energy input. It was found that in the fast transverse flow lasers the influence of turbulent diffusion was significantly smaller than the convective bringing the excited particles in the laser beam region.
