Laser oscillation on the C-A transition of XeF has been observed during direct excitation of Ar/Xe/F/sub 2/ and Kr/Xe/F/sub 2/ mixtures by microsecond electron beam pulses. The measured output energy was of the order of 1 mJ, and the laser performance was limited by the small magnitude of the net gain. Measured net gains in Ar/Xe/F/sub 2/ and Ne/Xe/NF/sub 3/ mixtures were < or approx. =5 x 10/sup -4/ cm/sup -1/ . Fluorescence and laser spectra of Ar/Xe/F/sub 2/ mixtures exhibited numerous absorption features. The laser emission intensity was maximum at approx.485 nm with an approximate 12-nm (FWHM) bandwidth. Substitution of Kr for Ar diluent dramatically improved laser performance.
