Abstract

Laser action on the CO vibrational‐rotational bands between 4.8 and 5.3 μ is produced by electrical excitation of CO : N₂ : O₂ : He mixtures followed by expansion in a supersonic nozzle. Conversion of electrical energy into laser output occurs with ∼ 2% efficiency and small‐signal gains in excess of 0.8% cm⁻¹ have been observed.
