Abstract

We propose a new method of beam smoothing based on spherical circular grating to reduce the perturbation in near field and focal plane. Our numerical simulation demonstrates that the smoothing effect using circular grating is better than that of 2D-SSD. The new method has potential application in inertial confinement fusion (ICF)..
