Axicon is a versatile optical element for forming a zero-order Bessel beam, including high-
power laser radiation schemes. Nevertheless, it has drawbacks such as the produced …

In recent years, vortex beams with orbital angular momentum (OAM) have attracted more
and more attention. The wavefront of the OAM beams is helical, the intensity at the center of …

Assembling and maintaining large arrays of individually addressable atoms is a key
requirement for continued scaling of neutral-atom-based quantum computers and …

Bessel beams are of great interest due to their unique non-diffractive properties. Using a
conical prism or an objective paired with an annular aperture are two typical approaches for …

The industrial maturity of ultrashort pulsed lasers has triggered the development of a
plethora of material processing strategies. Recently, the combination of these remarkable …

Propulsive effects of light, which often remain unnoticed in our daily-life experience, manifest
themselves on spatial scales ranging from subatomic to astronomical. Light-mediated forces …

Due to their immunity to diffraction, Bessel light modes potentially offer advantages in
various applications. However, they do exhibit significant intensity variations along their …

The extended focal depth of Bessel beams is a very attracting property for glass cutting
applications. However, Bessel beam generation with a non-ideal conical lens induces beam …

Abstract “Non‐diffracting” beams do not spread as they propagate. This property is useful in
many areas. Here, the theory, generation, properties, and applications of various “non …

The “perfect” vortex is a new class of optical vortex beam having ring radius independent of
its topological charge (order). One of the simplest techniques to generate such beams is the …
