Paper Abstract

A practical method for generating femtosecond-time-scale VUV pulses in the spectral range 150 - 200 nm is discussed. The method is based upon four-wave difference-frequency mixing in Xe ((omega) 3 equals 2(omega) 1 - (omega) 2). One can utilize a two-photon resonance in Xe to increase the VUV output energy by almost two orders of magnitude by choosing the beam at (omega) 1 to be a KrF-excimer-amplified ultrashort pulse. This resonantly-enhanced mixing process is utilized to generate is congruent to 4-(mu) J, femtosecond- time-scale, pulses at is congruent to 156 nm, suitable for use as seed pulses to test the ultrafast amplification characteristics of F2-discharges.
