Single- and double-channel laser-triggered switches in high-pressure gas were designed and operated in the voltage range from 1 MV to more than 3 MV. Jitter times of 1 to 3 ns were observed in most cases. Gas pressures of 150 psig and 300 psig were used. The gases were 100 percent nitrogen and a 41 mixture by partial pressure of N2 SF6 enriched with up to 50 percent argon. Significant accomplishments were 1 the simultaneous firing of four stages of a Marx generator by a multiply split laser-beam 2 up to 40 percent reduction of the risetime observed in the output pulse from a multimegavolt dc generator when switched into a load through two simultaneously laser-triggered channels and 3 the design and operation of a laser-triggered, dc-charged switch at more than 3 MV with subnanosecond jitter.
