Low power laser trigger switching of a solid insulated spark gap

Low power laser trigger switching of a solid insulated spark gap

The feasibility of reliably triggering solid dielectric insulated spark gaps by low power (∼6 MW) lasers has been demonstrated. Breakdown of 10‐mil Lexan dielectric sheets stressed to 70 kV was initiated by a focused 6 MW, Nd in YAG laser emitting 40 mJ in a pulse 6 ns wide at the half‐peak intensit...

Zusammenfassung:The feasibility of reliably triggering solid dielectric insulated spark gaps by low power (∼6 MW) lasers has been demonstrated. Breakdown of 10‐mil Lexan dielectric sheets stressed to 70 kV was initiated by a focused 6 MW, Nd in YAG laser emitting 40 mJ in a pulse 6 ns wide at the half‐peak intensity height. Delays achieved were in the tens of ns. Slight increases in laser power or electrical stress should produce shorter delays (
