In an experimental and analytical study of carbon monoxide CO lasers, the characteristics of the laser have been determined and the dominant mechanisms identified. The study shows that in an electrically excited CO laser, the population inversion occurs due to pumping of the lower vibrational levels by electron impact followed by an harmonic pumping to the upper lasing levels. Overall efficiencies up to 47 have been achieved at 77K. The small signal gains of the various vibrational rotational lines were measured. The populations of the lasing level were determined from these measurements and the saturation parameter was estimated from the gain measurements.
