A study of the operation of the XeF(B‐X) laser under low‐electron‐beam pump rate and high‐energy loading is reported. Measurements have been performed at pump rates of 36, 44, and 66 kW/cm3 with laser output pulse lengths greater than 4 μs in duration and energy loadings up to 280 J/l. Intrinsic laser efficiencies of 2.0% at 66 kW/cm3, 1.7% at 44 kW/cm 3, and 1.5% at 36 kW/cm3 were measured in optimized NF3, Xe, Ne mixtures. Under optimum conditions specific output energies as high as 5.6 J/l were measured. Gain and absorption were also measured.
