Abstract

For developing a new laser for laser cutting, which has the advantage of good beam quality, small size and low cost, we have proposed a round-metal-resonator CO₂ laser with blow-in discharge and spiral flow. In this paper, investigations have been made on the gain character of this laser. By solving the rate equations of the CO₂ laser and the 3D fluid mass and momentum continuous equations, the working conditions and structure parameters for circular uniformity distribution of small signal gain in the laser cavity have been provided.
