Paper Abstract

Experimental investigations of radio-frequency discharges in O2/He/NO mixtures in the pressure range of 1-100 Torr and power range of 0.1-2.5 kW have indicated that O2(a1Δ) production is a strong function of geometry, pressure and diluent ratio. The goal of these investigations was maximization of both the yield and flow rate (power flux) of O2(a1Δ) in order to produce favorable conditions for application to an electric oxygen-iodine laser (EOIL). As pressure is increased, yield performance is dominated by the influence of geometry and diluent ratio. Numerous measurements of O2(a1Δ), oxygen atoms, and discharge excited states are made in order to describe the discharge performance dependence on various parameters.
