Laser interferometry is favored for its non-contact, high-resolution, and dynamic range
capabilities. Vortex beams can enhance accuracy and robustness with their degrees of …

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 …

Skyrmions, topologically stable configurations of a three-component vector field with
sophisticated textures, have been considered in many contexts, including atomic physics …

We<? TeX 0pt 46.5 pc?> report the direct generation of vector vortex laser modes at 640 nm
from a compact, diode end-pumped continuous-wave P r 3+: L i YF 4 (YLF) laser that utilizes …

Precise control of amplitude and wavefront of optical fields are prerequisites for many
applications, especially in singular optics. This has led to the increasing efforts for …

We propose a novel micro-displacement measurement system that employs a modified
reversal shearing interference structure based on vortex beam interference. The micro …

We investigate the interference of high-order perfect optical vortex (POV) beams with
different topological charges. Through numerical simulations, we reveal a remarkable …

The generation of Bessel beams (BBs) and their characterization in a wide range of the
electromagnetic spectrum are well established. The unique properties of BBs, including their …

A light beam can be spatially structured in the complex amplitude to possess orbital angular
momentum (OAM), which introduces an extra degree of freedom alongside the intrinsic spin …

We report a q-plate-waveguide hybrid optical vortex emitter processed by femtosecond laser
directly writing the lithium niobate (LN) single crystal. Both simulation and experimental …
