Paper Abstract

A study on the space distribution of the excited xenon atoms on level 1s4 in a d.c. discharge in neon-xenon mixture is presented in this paper. The relative density of the excited xenon atoms was measured using diode laser absorption at 828.239 nm, corresponding to the xenon transition between 1s4 and 2p5 levels. A comparative analysis of the laser absorption signal and corresponding optogalvanic signal, permitted us to define a new parameter, namely optogalvanic effect efficiency, EffOG, as the size of the optogalvanic signal corresponding to an atom optically pumped by laser.
