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.
