Abstract

The transverse RF discharge plasma characteristics of He:N2:CO2 gas mixtures used in CO2 waveguide lasers has been predicted and measured. Using theoretical electron transport coefficients and a classical RF plasma model, predictions of discharge conductance, E/N, and excitation efficiency were obtained. Experimental values of gas conductance and E/N were reduced from measurements of laser voltage and input power. Laser efficiencies of 15% have been attained.
