TL;DR: In this article, the authors used optogalvanic detection of He Rydberg atoms in the cathode fall region of a glow discharge to measure the strength of discharge electric fields.
Abstract: Spatially resolved electric field measurements in the cathode fall region of a glow discharge are performed using optogalvanic detection of He Rydberg atoms. The large linear Stark effect of Rydberg levels provides an accurate, sensitive measure of discharge electric fields.

TL;DR: The behavior of these transitions can be separated into two general classes as mentioned in this paper : negative and positive, depending upon the particular state, and the magnitude is proportional to the probability of depletion of these levels by optical pumping.
Abstract: Irradiation of a neon‐supported, uranium hollow cathode discharge at wavelengths between 572 and 672 nm corresponding to optical transitions in neon or uranium causes significant changes in the impedance of the discharge. The behavior of these transitions can be separated into two general classes. (I) For transitions originating in the 1s levels of neon the impedance change is either negative or positive, depending upon the particular state, and the magnitude is proportional to the probability of depletion of these levels by optical pumping. (II) For other neon and all uranium transitions these impedance changes are negative and are proportional to the probability for absorption of laser radiation. Spatial variation of the impedance changes demonstrate the importance of collisions of the metastables with the cathode wall in maintaining the discharge.

TL;DR: In this article, a simple phenomenological theory of the optogalvanic effect based on the multiplication of an electron within the plasma is presented, and the dependence of the signal on current and pressure and its temporal behavior are predicted for atoms irradiated by chopped CW lasers and pulsed lasers.
Abstract: We present a simple phenomenological theory of the optogalvanic effect based on the multiplication of an electron within the plasma. The dependence of the signal on current and pressure and its temporal behavior are predicted for atoms irradiated by chopped CW lasers and pulsed lasers. Experimental data obtained by pulsed lasers are presented and interpreted.
