Abstract
We present a design of the diffractive phase elements (DPE's) that pro duce nondiffracting beams according to the beam-shaping scheme, in whi ch the incident Gaussian-profile beam is converted into a Bessel-funct ion J(0) beam. An optimization method is applied to solving this speci al beam-shaping problem. Numerical investigation of the generating J(0 ) Bessel beam shows that the designed DPE can satisfactorily produce t he J(0) Bessel beam. (C) 1998 Optical Society of America.
