Abstract

Provided is a gas switch triggered by an optical pulse introduced by an optical fiber, which solves the problem of the existing electrically-triggered gas switch and laser-triggered gas having a complicated trigger system, being insufficiently reliable and having a higher cost due to the pulse amplitude/laser beam energy having higher requirements. The gas switch triggered by an optical pulse introduced by an optical fiber includes at least one trigger gap and one self-breakdown gap; each trigger gap is connected in parallel to a photoconductive switch, and an optical fiber is correspondingly provided for introducing an optical pulse for triggering. In the present disclosure, the advantages of a low trigger requirement of a photoconductive switch and a high voltage and large conduction current of a gas switch are fully utilized, and an optical pulse introduced by an optical fiber is used to trigger the photoconductive switch, so that the gas switch can be controlled and triggered under the action of a low-energy optical pulse (which can be less than 200 μJ) transmitted by optical fiber, thereby greatly simplifying the scale and complexity of the trigger system and promoting the development and application of the pulse power supply technology.
