Experiments on a XeF (B → X) laser excited by a prepulse–main-pulse technique, including magnetic switching, are described. A parametric study of the laser output versus gas composition and electrical excitation was performed. We were able to increase the optical pulse length to typically 70 ns. The total output energy was typically 180 mJ (2.4 J/L) at an efficiency of more than 1.2%. The results demonstrate the possibility of a high average power gas-discharge XeF laser.
