Low Power Laser-Triggered Switching at Voltages > 500 kV

Abstract
The laser‐triggered switching of a 575 kV, Van de Graaff charged, high‐pressure, gas‐filled spark gap is described. Subnanosecond switch jitter could be maintained with laser powers of only 10 MW. The application of this technique to repetitive switching of high‐voltage, pulse‐power systems with nanosecond delay and subnanosecond jitter is considered.
