Lasing in KrF was obtained with a longitudinal, self-sustained, high-voltage discharge. The output powers and energies at 248 nm have been measured for some tube geometries as a function of different He, Kr, and F2 partial pressures and mirror reflectivities. A maximum laser energy of 50 μJ has been obtained by discharging a capacitor of 360 pF and 60 kV across a segmented discharge tube with a total length of 70 cm and 6.5 mm inner diameter.
