Gasdynamic CO laser utilizing hydrogen-containing active media

The gain of a gasdynamic CO laser utilizing a hydrogen-containing mixture was calculated using generalized data on the VT and VV relaxation times of CO and H₂ molecules. Deexcitation of excited carbon monoxide molecules by hydrogen atoms was taken into account. Laser emission was recorded experimentally from a CO gasdynamic laser utilizing the combustion products of an acetylene-oxygen mixture diluted with argon.
