Spectral distribution of a high pressure CO2 laser: experiment and theory
Abstract
The spectral characteristics of a 10-atm CO2 laser have been studied. The gain minima reveal broadening and splitting tendencies of the line, correlated with a spatial deformation. These effects are quantitatively explained by a theoretical model which underlines the role of transverse modes higher than TEM on the spectral distribution. Analytical formulas are developed, which can be used for any type of homogeneously broadened lasers.
