Abstract :
A technique for improving the output uniformity in fast-discharge large-aperture lasers is described. Spatial variation of the X-ray preionization flux is used to compensate for the discharge-plasma skin depth and nonuniformity in the initial electric-field distribution. The technique was demonstrated using a 4.25×4.25 cm clear-aperture KrF laser that produces 2.7 J in a 15 ns FWHM pulse
