Abstract: The optogalvanic signal (OGS) induced in a uranium-neon hollow-cathode discharge was measured as a function of the laser power density for the 0→16900 cm-1 (591.5 nm) uranium transition. Theoretical relations derived by solving a two-level system rate equations showed the OGS dependence on the laser photon flux, for a modulated c.w. light and for stimulated transitions starting from the ground state. A fitting of the theoretical relations to the experimental measurements allowed the determination of the σ0τ product, that is, the saturation parameter of the transition. The results showed good agreement between the σ0τ values obtained by the optogalvanic and the usual optical absorption processes. © 1992 Società Italiana di Fisica.
