10 x 10 cm-sq aperture 1 Hz repetition rate X-ray preionized-discharge pumped KrF excimer laser
Abstract
A 10 x 10 sq cm aperture X-ray preionized discharge-pumped KrF excimer amplifier for subpicosecond pulse amplification is demonstrated experimentally in the oscillator mode operation. A fast pulse-forming line (36 nF, 340 kV) together with a peaking capacitor (6 nF) switched with a rail-gap switch, and collimated X-ray preionization is employed to obtain a wide and uniform discharge. The active cross section of the laser beam is about 10 x 8 sq cm and the intense plateau region is about 10 x 5.5 sq cm. The laser pulse energy exceeds 4.7 J in a 28 ns pulse (FWHM).
