Abstract
Various approaches for flattop beam generation have been reported.1-4) Here we focus on a grating approach in which a phase grating is used to modulate a beam wavefront and shape its Fourier spectrum. We designed a grating-type beam shaper in an iterative manner, where an optimal grating phase is sought under the constraints of amplitude and phase both in the grating and Fourier planes.
