Non-diffractive Vector Bessel Beams
Zdeněk Bouchal,Marek Olivík +1 more
TL;DR: In this article, the non-diffractive vector Bessel beams of an arbitrary order are examined as both the solution to the vector Helmholtz wave equation and the superposition of vector components of the angular spectrum.

Propagation-Invariant Optical Fields
TL;DR: In this paper, Turunen and Friberg dealt with a class of fields with propagation-invariant properties such as the optical intensity distribution and applied them to scalar and electromagnetic approaches.
Journal ArticleDOI
Experimental investigation of Bessel beam characteristics.
TL;DR: It is shown that real Bessel beams can be generated with intensity profiles that closely resemble the ideal J(0)(2) transverseintensity distribution of Bessel beam beams.
Journal ArticleDOI
Propagation of apertured Bessel beams
TL;DR: The propagation features of several apertured Bessel beams are calculated and show that the relations of axial intensity versus propagation distance are similar to the radial distribution of the aperture functions, which may be helpful in choosing the proper aperture functions in experiments.
Journal ArticleDOI
Generation of nondiffracting beams by diffractive phase elements
TL;DR: In this article, the diffractive phase elements (DPE) were designed to produce non-iffracting beams according to the beam-shaping scheme, in which the incident Gaussian-profile beam is converted into a Bessel-function J0 beam.

Diffraction-free beams.
TL;DR: The first experimental investigation of nondiffracting beams, with beam spots as small as a few wavelengths, can exist and propagate in free space, is reported.

Exact solutions for nondiffracting beams. I. The scalar theory
TL;DR: In this paper, exact nonsingular solutions of the scalar-wave equation for beams that are non-diffracting were presented, which means that the intensity pattern in a transverse plane is unaltered by propagating in free space.

Refracting systems for Gaussian-to-uniform beam transformations
S.R. Jahan,Mohammad A. Karim +1 more
TL;DR: Two refracting optical systems have been designed to convert a circularly-Gaussian laser beam into a circle-uniform laser beam and an annular Gaussian beam into circularly uniform laser beam.
