Abstract
The development of a compact, all solid-state switch system that has switched up to 8.5 MW into a 38- Omega load is described. The system uses a 2-D laser diode array with a peak power of 850 W to trigger a 1.5-cm-long GaAs photoconductor into a high-gain conduction mode known as lock on. The highest power switch was pulse-charged to 55 kV and delivered 470 A to a 38- Omega load in a 160-ns-long pulse.Keywords
