A simplified theoretical model for the laserinduced optogalvanic effect
Abstract
A simplified theoretical model for an estimate of the optogalvanic effect induced in an electric discharge by resonant laser radiation is presented. This theory is based on the solution of a twolevel system rate equation, where the upper level of the stimulated transition is connected to the ground state (lower level) through radiative and collisional processes. The developed relations show that the magnitude and temporal evolution (in the case of pulsed excitation) of the optogalvanic signal depend on the electronic plasma density, electron temperature and on the density of light absorbing centers.
