Abstract: The principle and technique of irradiation uniformity for laser driven fusion are analysed.Kinoform phase plates (KPP) is studied by using theoretical analyse and numerical calculation.The results show that the converged far-field pattern containe more than 96% of the incident energy inside a desired region and the minimum nonuniformity is about 14%.Reviews on irradiation uniformity of the laser driven fusion device are covered.

Key words: irradiation uniformity, computational study, kinoform phase plates
