Analysis of the Factors Causing Glow Collapse in High Energy Electron Beam Sustained CO Lasers.

Abstract

In this investigation the causes of thermal instability in high power CO laser discharges were examined. This analysis showed that externally sustained CO laser discharges are inherently unstable, having instability-growth times on the order of 0.1 msec. The single most important factor affecting instability growth at a specific power density level was found to be electron-positive ion recombination. Changes in the recombination process as a consequence of positive ion kinetics were found to result in order of magnitude variations in instability growth. Because of the importance of recombination the effects of ion clustering reactions and water-ion chemistry are discussed in detail. (Author)
