ABSTRACT
Effects of a pressurized spark switch on N2 laser output have been observed optically with quartz fibers. The output power increased with decreasing the gap of the spark switch while keeping pgd=0.51 kg/cm (pg is the N2 gas pressure in the spark switch and d is the gap distance) and pN2=40 Torr (pN2 is the pressure of the laser medium gas). One nanosecond pulses with peak powers of 120 kW have been generated for the first time for low-pressure operating N2 lasers.
