Abstract: The optogalvanic signal (OGS) induced in a Ti-Ar hollow-cathode discharge, stimulated by modulated cw laser light tuned to the a P-3(0-y) (3)D(1)degrees Ti I transition, was measured as a function of the light intensity. By solving analytically the rate equations of a three-level system, which include the Ti I ground state, the lower metastable a P-3(0) and the upper y (3)D(1)degrees levels, an expression was obtained that relates the magnitude of the OGS to the laser intensity and the saturation parameter (1/sigma(0)tau). The sigma(0)tau product was determined by fitting the theoretical curve to the experimental data.
