Abstract
The rate coefficients for collision induced transitions from a laser level to neighboring levels of active medium particles are theoretically connected with the intensity of the spontaneous emission originating from these levels and its variation due to 100% modulation of the laser oscillation. The levels pertaining to the configuration 4s 2 4p 2(2 P)5p of Se2 are explored at conditions of operation of a positive column He-Se+ laser. Normalized population transfer rate coefficients are defined. Their values are obtained based on the measured spontaneous emission intensity and its variation. The dominating partners for the mixing collisions with excited selenium ions are suggested as Se+, Se and He+ in contrast with the free electrons and helium atoms.
