Paper Abstract

The molecular processes that increases a discharge current by photoelectron detachment of negative ions and decreases the current by photodissociation products could be applied for the development of fast and high repetition-rated opening switches. To demonstrate this principle, a switching of electron conduction current by laser irradiation on a DC discharge medium was investigated. The discharge current sharply increased after the discharge medium was irradiated by a laser pulse, and then decreased to a small fraction of the original DC current. Our results show that the magnitude and pulse duration of a current switching can be controlled by SOC12 pressure, laser power, and laser interaction volume.
