This report presents results of an experimental program to explore the lasing potential of the C02 0,0,V3 C02 0,0,V3-1 a symmetric stretch bands in a cooled electrical glow discharge. The C02 0,0,V3 level populations were measured by infrared emission spectroscopy from V3 0 1 to V3 approximately 10. The influence of flow velocity, dishcarge current density, and wall temperature on the populations was measured. It was found that these states do enter a vibration-to-vibration pumped partial population inversion, which is enhanced at lower temperatures. However, states above V3 approximately 10 do not appear pumped, and the inversion was insufficient to achieve laser oscillation in the apparatus used. Alternate experimental configurations which may achieve lasing on these bands are suggested. Author
