An important technique required in the application of laser systems to fusion is the ability to generate high energy to satisfy the conditions for self-ignition and to improve the uniformity of laser irradiation. To achieve this result, it is necessary to introduce a kinoform phase plate (KPP) that is able to produce an optimum envelope profile. However, a KPP is sensitive to beam aberrations caused by the nonlinear refractive index in optical components. To overcome this problem we have developed a multi-segmented KPP and demonstrated its usefulness and strength against phase distortions by numerical simulations.
