An Experimental and Theoretical Investigation of Optogalvanic Effects
Abstract
Optogalvanic effects are changes in the conductance of a gas discharge caused by absorption of light via a bound state - bound state transition of an atom or molecule. Optogalvanic effects of both signs are observed. Negative effects, which correspond to a decrease in discharge conductance, are of particular interests for application in pulsed power switching. Research on optogalvanic effects has resulted in (1) a better understanding of the interaction of laser radiation and gas discharges, (2) the discovery of a mechanism for amplifying optogalvanic effects, and (3) the development of powerful new gas discharge diagnostics based on optogalvanic detection of Rydberg atoms. The amplified optogalvanic effects, which occur in the cathode fall, constitute a promising area for further research.
