Abstract:
A radiation-collisional model of the resonant gas ionization by laser has been constructed assuming radiation transfer conditions. A numerical algorithm of solving the problem has been developed for the case of cylindrical geometry of a medium. It was established, that free electrons are formed due to associative ionization. Then the electrons heat up at the second-kind collisions and ionize atoms when colliding. The effect of resonant radiation (with λ = 589.6 nm) transfer on the kinetics of sodium vapor clearing under ionization-caused clearing-up has been studied for the case of ionizing atoms by an electron avalanche.
