The work summarizes analytical and experimental studies of the compression and rarefaction waves which occur in a pulsed CO electric discharge lasers cavity. The one-dimensional, acoustical analysis includes localized heating around the cathode, heat transfer to the cathode, flow through both the cathode and anode, and bulk heating of the plasma. With the aid of the analysis, bulk heating rates of CO lasing mixtures were calculated for various temperatures and pressures. Results from experimental studies of a Northrop pulsed CO laser were used. Heating rates are presented for Argon-CO, N2-CO, and N2.
