Abstract:

This report contains a brief review of the results obtained in this program which was designed to examine prospective high power, high efficiency laser media. These studies included measurements of the optical emissions and temporal behavior of excited state in dense vapors and gas mixtures excited by intense, pulsed electron beams. In addition, detailed models of the excitation, relaxation, and decay kinetics of excited states have been realized for the case of AR-N2, Xe-O2, and Xe-Hg mixtures. We also examine in detail the spectral and temporal properties of emissions coming from mixtures of Xe and Hg, a prototype of rare gas-metal atom excimer systems, and determine some relevant rate constants. Significant fluorescent yields from weakly bound Xe-Hg excimer radiations suggest the possibility of a good UV pump source near 270 nm which could be used for photolytic production of I2P12. A model of the energy pathways has been constructed, and it is concluded that laser action may be possible on the bands arising from the Hg 7 3S levels.
