Abstract
A new technique to achieve smooth laser irradiation profiles on laser fusion targets is evaluated numerically and experimentally. In this te chnique, smoothing is obtained by using a spectral dispersing optic an d a random-phase plate placed in front of a focusing lens employing th e broad-bandwidth of KrF lasers. Experimental results and numerical ca lculations agree well, verifying that this simple optical system is ef fective for smooth irradiation on targets.
