Nanolites, spark channels that produce intense light flashes of very short duration, were investigated to obtain a physical understanding of how their characteristics could be adjusted. After designing a spark circuit that gave maximum current rise, a set of nanolites of different capacities were constructed to stand the various steps of the spark breakdown. The high resistance prechannel was found to be transparent and subnanosecond light pulses produced by such prechannels closely followed the shape of the current pulse. Author
