Smoothing by spectral dispersion using random phase modulation for inertial confinement fusion

Summary form only given. 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. In this paper it is shown that implementing smoothing by spectral dispersion (SSD) with random-phase modulation (RPM) achieves the same smoothing rates at low spatial frequency as that of the induced spatial incoherence (ISI) method.
