Paper Abstract

The paper concerns with qualitative laser induced fluorescent spectroscopy of the atomic systems in a H.C. electric discharge plasma. Some effects of a neon hollow, cathode plasma - He-Ne laser interactions, are shortly presented. We can see how the stimulated processes perturb selectively the nonlasing high levels and allow to investigate the dependence of upper or lower laser levels on some processes in a hollow cathode spectral source. A significant dependence on the curren intensity or elctron concentration of some Ne spectral lines intensities as NeI 5944.83 Å and Ne 6096.16 Å coupled with the laser line Ne 6328.16 under laser irradiation is marked. This behaviour of the spectral line intensities is similar to that obtained in the Ne afterglow plasma - He-Ne laser interaction.
