A simplified model of a high pressure CO2-N2 laser pumped by a discharge controlled by a beam of electrons
Abstract
A three-level model of the CO2-NO2 molecular structure is employed; relaxation of energy associated with the pressure of water steam is considered. It is established that the increase of pressure of the compound up to ten atmospheres does not induce new processes as compared with low pressure lasers, and speeds of processes with respect to one molecule do not change. Solutions of a five equation system, to which the model is reduced, are compared with experimental results. Good qualitative and quantitative agreement is attained after disregarding the adhesion process and the triple increase of the recombination factor. The model clarifies many aspects of laser physics and can be used to optimize work conditions in the pressure range of one to ten atmospheres.
