Abstract

Direct laser driven ICF system requires a high degree of uniformity in laser energy in order to avoid Rayleigh-Taylor instability. In all-fiber laser driven ICF system, millions of fibers are fixed around the target chamber. We suggest the fibers are arranged in bundles with a single lens coupling the output of a bundle. If the arrangement is optimized, top-flat intensity profile is acquired near the focus of the lens. Least square method is used here in determining the optimum values of relative parameters. Factors on the irradiation nonuniformity are also analyzed here by numerical simulations.
