Abstract : In any type of a gas discharge, dissociative products reduce gaseous reactant concentrations resulting in cessation of the desired reaction. In a CO2 laser, dissociation of the CO2 molecule results in increased concentrations of CO and O2 while reducing the CO2 concentration. As the CO2 concentration decreases so does power output of the device. From a purely chemical standpoint, the process of dissociating CO2 in an electrical discharge should be completely reversible, i.e., 2CO2 = 2CO + O2 + E, where E represents the exothermic energy of dissociation. The research reported was directed towards determining if the reaction could be reversed by employing an internal catalyst. Previous correlations between increased laser output and platinum elements within the plasma were shown to be misleading. (Author)
