An overview of KrF laser issues for fusion in the laboratory environment is presented. In this fusion method, lasers are used to compress the deuteriumtritium fuel in the pellet to several thousand times its initial density. Krypton-fluoride lasers offer favorable wavelength, bandwidth, pulse-shaping, efficiency, and high-repetition rate properties for achieving fusion. Large-scale demonstration plants for fusion, however, rely on the improvement or resolution of significant issues: front-end capabilities, amplifiers and amplifier scaling, optical engineering for the ultraviolet, alignment systems, kinetics, beam quality, target coupling, cost, and overall system factors. We feel that KrF lasers may be able to meet the required inertial confinement fusion driver characteristics, driver-target coupling particularities, and capsule physics issues necessary to achieve the final conditions in the implosion that will produce net energy release from the fusion reaction.
