Abstract
We report on the theory and development of a diffractive element compo sed of a binary phase zone-plate array. This component conditions the intensity distribution in the focal plane of a conventional refractive lens to generate efficiently (82%) a flattop intensity envelope on ta rget. Analysis of the design indicates that manufacturing tolerances a re not critical. Experimental performances on target from x-ray emissi on and shock-breakout measurements are also presented.
