Photonic-crystal-fiber-delivered laser-triggered high-voltage gas switch

摘要

A photonic-crystal-fiber-delivered laser-triggered high-voltage gas switch can deliver a peak irradiance of greater than 5.1×10¹¹ W/cm² to the AK gap for a laser having a wavelength of 1064 nm. The switch is capable of operating at pressures up to 2200 psi; voltages across the gap of greater than 200 kV; operation at less than 70% self-break voltage; shot-to-shot jitter of less than 3 ns; AK gap distances of 3 mm or smaller; and triggering via a fiber-delivered laser pulse energy of as low as 500 μJ.
