Abstract

Abstract: A hybrid method which collects the advantages of both iterative method and optimization method is introduced.This method is adopted in designing the diffractive optical device used in target illumination of ICF system,and better design results are obtained.The diffractive efficiency is up to 97.5%,the mean square error is 0.026 and the focal plane profile has an perfectly flat top.

Key words: iteration, optimization, phase mixed algorithm, simulation annealing method
