Abstract : The patent describes a radioactive preionization method and apparatus for pulsed gas lasers. Emissions from a radioactive isotope located within or around the gas-laser active volume are used to create a constant, uniform preionization in the laser gas and aids the formation of the main electrical discharge pulse. The pulsed electrical discharge will hence be caused to be more spatially uniform in intensity, less prone to form discharge filaments and arcs, more repeatable from pulse to pulse, and capable of operating more satisfactorily at higher gas pressures than one not subjected to radioactive emission preionization.
