Observation of CW laser action in chlorine, argon, and helium gas mixtures

CW oscillation on several lines from 1.9 to 3.1μ has been attained in mixtures of Cl, He, and A. Power outputs up to 65 mW have been observed at 2.45μ in a 187-cm-long by 2.5-cm-diameter laser. Evidence of energy transfer between A and Cl has also been observed.
