Flattened gaussian beams
TLDR
In this paper, a simple propagation law is found for light beams of various orders and their field distribution across the waist plane is similar to that produced by an ordinary gaussian beam except that the central region is flattened.About:

Light sources generating far fields with tunable flat profiles
Serkan Sahin,Olga Korotkova +1 more
TL;DR: Planar, scalar, optical Schell-model, and quasi-homogeneous sources with correlations that are Fourier transforms of multi-Gaussian functions are introduced and it is demonstrated that far fields produced by these families of sources carry interesting characteristics.

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.

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.

Optical Vortices and Their Propagation
TL;DR: In this paper, the free space propagation of an array of optical vortices nested in a smooth (Gaussian) beam is studied in the paraxial regime, and it is shown that their relative positions, as well as their positions within the host beam are invariant upon propagation.
