A XeF(B→X) laser efficiency of 6.0% has been observed in an electron beam pumped device. This is the highest XeF(B→X) laser efficiency reported to date. Mixtures of NF3 , Xe, and Ne at 425 K and a density of 3 amagat were pumped at a rate of 280 kW/cm3 with a 550 ns pulse. This deposited 150 J/l into the laser gas. Subsequent experiments at 190 J/l input (and 460 K) yielded specific laser outputs as high as 11 J/l.
