The kinetics of physical processes in pinch-discharge lasers is investigated. An analytic solution is proposed for the relaxation problem of the population of discrete levels of ionized argon (ArII) in rapid compression of a high-temperature nonequilibrium plasma. An expression for population inversion as a function of the parameters of the plasma and unit is obtained on the basis of the solution and also of a simplified model for the compression of a plasma column. Basic experimental dependences for pinch-discharge lasers are analyzed.
