Paper Abstract

Experimental and theoretical investigations were made of a radial inhomogeneity of the gain in a cw CO2 laser with fast axial flow. The results showed that this inhomogeneity was the result of a radial inhomogeneity of the temperature and of contraction of a longitudinal self-sustained discharge towards the axial region in a gas-discharge tube. This caused saturation of the rise of the small-signal gain when the discharge current was increased. It also reduced the rate of the output radiation power with increase in the input energy when the fundamental Gaussian mode was generated.
