Abstract

Abstract: A grazing incidence, shallow liquid metal mirror could be used as the final optic for the heating laser in a fast-ignition fusion power plant. The relaxation of vibrations on the surface of liquid mercury following laser irradiation was measured experimentally in this study. The results suggested that vibrations on a 0.25-mm-thick mirror were small enough to allow 4-Hz laser operation.
