Abstract

Inertial confinement fusion (ICF) utilizing direct or indirect laser drive requires the target illumination to be uniform over a wide range of spatial frequencies. A number of approaches have been suggested to achieve the desired level of illumination uniformity.¹⁻⁵Angular dispersion of phase-modulated light (termed smoothing by spectral dispersion –SSD)⁵ is attractive for ICF using glass lasers because phase modulation preserves the uniform intensity profiles necessary for high-power laser amplification.
