Abstract

We show that extraction of energy in the form of a train of subnanosecond pulses from a discharge-pumped KrF excimer amplifier is an efficient means of enhancing the intensity of the laser radiation. The effect of interpulse time separation and pulse width are investigated experimentally. Intensity enhancements of up to 7x above steady-state, with extraction efficiencies in excess of 60% of the steady-state value, were obtained by amplifying a train of 0.4-nsec full-width-at-half-maximum (FWHM) pulses separated by 5 nsec.
