Abstract

An enhanced turbulence fast axial flow CO₂ laser has been developed. The new helical cascaded metal discs discharge tube formed by hard anodized aluminum discs promises higher hold-off voltage, larger effective active volume, and good thermal conduction. The specific laser power has attained 1100 W/m for 2.1 cm tube diameter. Theoretical calculation of the effects of turbulent flow on the radial distribution of electron density, gas temperature, and small signal gain are presented.
