Abstract

The degree of dissociation of CO2 in a sealed CO 2-N2-He laser is limited by catalysis of reactions re-forming CO2, either by a platinum cathode or with outgassed hydrogen. The degree of dissociation measured in a laser is in quantitative agreement with that calculated for the reactions occurring in the discharge plasma if 5% of the hydrogen is in the atomic form. The hydrogen partial pressure is controllable by a palladium diffusion tube.
