ABSTRACT:
An ultraviolet preionizer for high power gas lasers. The preionizer is a spark gap array or groups of arrays adapted to be fired preceeding the main discharge pulse of the laser. A fast energy dump to the spark array results in efficient ultraviolet light production. The spark gaps of an array are automatically fired in sequence providing a series current path through the gaps to dump the energy, while providing an electrical glow discharge at each gap for ultraviolet emission.
