Wx. Cong et al., GENERATION OF NONDIFFRACTING BEAMS BY DIFFRACTIVE PHASE ELEMENTS, Journal of the Optical Society of America. A, Optics, image science,and vision., 15(9), 1998, pp. 2362-2364
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.
