TLDR
In this paper, the propagation of a combined beam consisting of two coaxial Bessel Gauss and Laguerre Gauss vortex beams is investigated and it is demonstrated that the vortical properties of light field under diffraction depend on propagation length as well as on amplitude ratio of individual beams.About:

Analysis of orbital angular momentum of a misaligned optical beam
TL;DR: In this article, an analysis of the orbital angular momentum of an optical beam misaligned with respect to a reference axis is presented, where both laterally displaced and angularly deflected Laguerre-Gaussian beams are represented in terms of the superposition of azimuthal harmonics with well-defined orbital angular angular momentum.

Partially coherent standard and elegant Laguerre-Gaussian beams of all orders
TL;DR: The results indicate that an elegant LG beam spreads slower than a standard LG beam, while this advantage disappears when their initial coherences are very small, and may find applications in connection with laser beam shaping, singular optics and astronomical measurements of angular momentum of radiation.

Convergence of general beams into Gaussian intensity profiles after propagation in turbulent atmosphere
TL;DR: In this paper, it is shown that a general shaped laser beam will eventually approach a Gaussian average intensity profile after propagation in turbulent atmosphere, where the source field at the exit plane of the laser is taken as the product of arbitrary functions of source transverse coordinates with Gaussian exponential modulations.

Average Intensity and Spreading of Partially Coherent Standard and Elegant Laguerre-Gaussian Beams in Turbulent Atmosphere
TL;DR: In this paper, the average intensity, mean squared beam width and angular spread of partially coherent standard and elegant Laguerre-Gaussian (LG) beams propagating in turbulent atmosphere are derived.
Journal ArticleDOI
Generation of self-imaged optical bottle beams
TL;DR: In this paper, a self-imaged optical bottle beam is generated by interfering two Bessel beams with varying radial propagation constant or radial frequency, where the optical bottle beams have on-axis intensity minima along the propagation direction surrounded with regions of higher intensity.

Dislocations in wave trains
John F. Nye,Michael V Berry +1 more
TL;DR: In this paper, it was shown that dislocations are to be expected whenever limited trains of waves, ultimately derived from the same oscillator, travel in different directions and interfere -for example in a scattering problem.

Bessel-Gauss beams
TL;DR: In this paper, a new type of solution of the paraxial wave equation is presented, which encompasses as limiting cases both the diffraction-free beam and the gaussian beam.

Marat S. Soskin,Vyacheslav N. Gorshkov,Mikhail V. Vasnetsov,J. T. Malos,Norman R. Heckenberg +4 more
TL;DR: In this article, the properties of light beams carrying phase singularities, or optical vortices, were studied both in theory and experiment, and the general rule for angular-momentum density distribution in a combined beam was established.

Optics of light beams with screw dislocations
TL;DR: In this paper, the screw dislocations of different charges produced by diffraction on the computer-synthesized grating or by nonlinear processes of second- harmonic generation are experimentally studied and discussed.
