Studies of the Acoustic Waves Formed in an Electric Discharge CO Laser Cavity

Abstract

The work summarizes analytical and experimental studies of the compression and rarefaction waves which occur in a pulsed CO electric discharge laser's 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.
