TLDR
In this paper, the structure and mechanical properties of a light beam, which is forcedly rotated around the propagation axis, are considered on the ground of the beam representation by superposition of axially symmetric optical-vortex beams (for example, Laguerre-Gaussian modes) with concertedly shifted frequencies.About:

Atoms in complex twisted light
TL;DR: In this article, a review of the physical properties of twisted light is presented, focusing on how such tailored forms of light can exert a controllable influence on atoms with which they interact.

Controlling the topological charge of twisted light beams with propagation
TL;DR: In this paper, a class of light beams, known as frozen waves, whose intensity and topological charge (sign and magnitude) can be controlled along the propagation direction, at will.

Direction-sensitive transverse velocity measurement by phase-modulated structured light beams.
TL;DR: A novel method that uses dynamic control of the phase in the transverse plane of the structured light beam so that the direction of the particles' movement can be deduced and can be used with other types of motion.
Journal ArticleDOI
Radially dependent angular acceleration of twisted light.
TL;DR: A simple approach to control the angular acceleration of light using Laguerre-Gaussian modes as twisted beams carrying orbital angular momentum, and shows that superpositions of opposite handedness result in a radially dependent angular acceleration as they pass through a focus.

Orbital angular momentum of light and the transformation of Laguerre-Gaussian laser modes.
TL;DR: Laser light with a Laguerre-Gaussian amplitude distribution is found to have a well-defined orbital angular momentum and an astigmatic optical system may be used to transform a high-order LaguERre- Gaussian mode into aHigh-order Hermite-Gaussia mode reversibly.

Astigmatic laser mode converters and transfer of orbital angular momentum
TL;DR: In this paper, a mode converter based on the Gouy phase was proposed to transform a Hermite-gaussian mode of arbitrarily high order to a Laguerre-Gaussian mode and vice versa.

Mechanical equivalence of spin and orbital angular momentum of light: an optical spanner.
TL;DR: It is shown that the spin angular momentum of +/-?per photon associated with circularly polarized light can add to, or subtract from, the orbital angular momentum to give a total angular momentum.

TL;DR: In this paper, an isolated dark ring is created within a light beam, with an analytical description of the field, and a screw wave-front dislocation has a feature that the spatial structure of the wave front has the form of a helicoid around the dislocation axis.
