Plasma Chemistry Processes in pulsed Electric Discharge Lasers.
Abstract
A theoretical model is developed to analyze plasma chemistry effects on the performance of pulsed, electron-beam sustained, electric discharge lasers. Predicted single pulse performance for a CO2 laser oscillator at 5 atm is found to be in excellent agreement with experiment. Analysis of several potential laser gas mixtures containing hydrogen in place of helium indicated that closed cycle operation and repetitive pulsing leads to a strong degradation of laser performance due to formation of electrophilic species. Important contaminants are identified, and their selective removal is shown to prevent degradation of laser performance. (Author)
