Abstract

We estimate the adaptation of the kinoform phase plate (KPP) for direct irradiation of the spherical target. The KPP has the focusing depth of about 200 micrometers in Gekko XII irradiation system. This corresponds to the radius of typical target. The optimum KPP is designed by using the direct-search method. The KPP removes the nonuniformity of 6th spherical mode.
