Abstract
Binary phase Fresnel zone plate arrays have been used recently to gene rate circular top hat intensity profiles for high intensity laser irra diation of targets. A simple analysis of these binary phase zone plate s using diffraction theory is presented and used both to optimise the uniformity of the focal spot by modifying the Fresnel zone structure a nd to produce noncircular foci.
