The efficient generation of stimulated emission from XeF at 351 and 353 nm has been achieved by pumping RG/Xe/NF3 gas mixtures (RG=argon, neon, or helium) with an intense (∼10 A cm-2) beam of ∼200-keV protons. For an active medium (T=300°K) consisting of Ar, Xe, and NF 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 -3, respectively. Much lower efficiencies were obtained for neon and helium diluent mixtures.
