Electric-discharge gasdynamic laser utilizing transitions between coupled-mode levels of the CO2 molecule

Lasing was observed for the first time in a quasi-cw electric-discharge gasdynamic laser in the spectral range 16.3–16.9 μ. The lasing was due to transitions between coupled-mode levels of carbon dioxide gas and it was observed on excitation of CO₂–Ar (Ne,Xe) mixtures by a glow discharge.
