We present a design of the diffractive phase elements (DPE’s) that produce nondiffracting beams according to the beam-shaping scheme, in which the incident Gaussian-profile beam is converted into a Bessel-function beam. An optimization method is applied to solving this special beam-shaping problem. Numerical investigation of the generating Bessel beam shows that the designed DPE can satisfactorily produce the Bessel beam.
