title: Design of the diffractive optical elements for synthetic spectra.
abstract: We present a novel efficient gradient-based optimization algorithm for the design of diffractive optical elements (DOE's) for synthetic spectra applications. Two design examples are given. The results demonstrate that the DOE's obtained by the proposed algorithm can accurately produce the desired intensity spectra at a predetermined diffraction angle.
