The efficient generation of stimulated emission from XeF at 351 and 353 nm has been achieved by pumping RG/Xe/NF/sub 3/ gas mixtures (RG=argon, neon, or helium) with an intense (approx.10 A cm/sup -2/) beam of approx.200-keV protons. For an active medium (T=300 /sup 0/K) consisting of Ar, Xe, and NF/sub 3/ at a total pressure of 1 atm and 30% cavity output coupling, the volumetric output, efficiency, and threshold pump power for the laser were determined to be 5--10 J/liter amagat, 1.7 +- 0.7%, and 1.5 MW cm/sup -3/, respectively. Much lower efficiencies were obtained for neon and helium diluent mixtures.
