Over the past 36 years much research has been carried out on Bessel beams (BBs) owing to
their peculiar properties, viz non-diffraction behavior, self-healing nature, possession of well …

We provide a simple analysis based on ray optics and Dirac notation for 1D (one-
dimensional) and 2D (two-dimensional) non-diffracting modes in the cosine profile, which …

Using the asymptotic formula of the Hermite polynomials for higher-orders n≫ 1, an elegant
mathematical expression that makes Hermite–Gaussian beams and cosine beams …

It has been known for some time that Bessel–Gaussian beams and their associated families
self-heal after encountering obstacles. Recently, it has been shown theoretically and …

We provide a simple analysis based on ray optics and Dirac notation for one and two-
dimensional Cosine beams. We then went on to understand the properties of the Bessel …

A novel technique to improve the focus depth of a Gaussian beam is presented in this paper.
The improvement is based on two-step beam shaping using a cascade of binary phase …

We consider the transformation of a Gaussian laser beam into a flat-top intensity profile or
into an optical bottle beam (OBB) by resorting to a diffractive or an interferometric method …

Alongside the well-known solutions of standard beams, elegant Gaussian beams (eGBs)
have been presented as alternative solutions to the paraxial wave equation. In this work, we …

Let us consider the family of symmetrical Laguerre-Gaus modes of zero azimuthal order
which will be denoted as LG p0. The latter is made up of central lobe surrounded by p …
