Spectral distribution of a high pressure CO(2) laser: experiment and theory.
The spectral characteristics of a 10-atm CO(2) 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(00) on the spectral distribution. We have developed analytical formulas which can be used for any type of homogeneously broadened lasers.
