Abstract

Ongoing experiments have led to continued improvements in the Electric Oxygen-Iodine Laser (ElectricOIL) system that significantly increased the performance, gain, and laser power output. Experimental investigations utilize radio-frequency discharges in O2/He/NO mixtures in the pressure range of 30-60 Torr. 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 subsequent gain and lasing in our ElectricOIL system. Numerous measurements of O2(a1Δ) ,oxygen atoms, and discharge excited states are made to characterize the discharge. A gain of 0.22% cm-1 was measured with a corresponding outcoupled power of 28 W. Modeling with the BLAZE-IV model is in good agreement with data and helps to guide our understanding of this complex hybrid laser system.
