OPTICAL-PUMPING OF MIXTURES CONTAINING CO BY MULTIFREQUENCY CO LASER-RADIATION

An experimental investigation was made of the optical pumping of a str eam of a gas containing CO by cw CO laser radiation. An analysis and n umerical modelling made it possible to reproduce the experimentally de termined distribution of molecules between the vibrational levels. The experiments on pumping of pure CO could be explained only when the sp atial distributions of the parameters along the gas stream were taken into account.
