Paper Abstract

The efficiency of the four-wave mixing (2 (omega) 1 - (omega) 2), VUV femtosecond source described by us last year (SPIE Vol. 1861) inherently relies upon a two-photon resonance enhancement occurring (in Xe gas) when (lambda) 1 approximately equals 248.5 nm. However, it also depends upon the spatial and temporal coherence properties of the input pulses. Development of a new source for producing beams at (omega) 1 with greatly improved coherence properties is reported here. Performance of the four-wave mixing source with these (omega) 1 pulses is described. Femtosecond VUV pulses with energies as high as approximately 60 (mu) J are generated. As a separate topic, we propose the use of a pulsed (nanosecond) infrared laser to deplete the terminal state of an F2 (157-nm) laser in order to greatly enhance its performance.
