The construction is described of a simple and compact KrF laser with electron beam excitation. The electron beam is generated in a coaxial vacuum diode, driven directly by a ten-stage coaxial Marx generator. A flat MgF2 outcoupler and a suprasil roof prism, protected by an MgF2 window, proved to be resistant against optically and chemically induced damage. A gas mixture of 4.5 bar Ar, 150 mbar Kr and 10 mbar F2 gives an energy output of 0.46 J from a 16 cm3 volume in 40 ns pulses or 0.72 MW/cm3.
