Non‐Gaussian beam profiles such as Bessel or annular beams enable novel approaches to
modifying materials through laser‐based processing. In this review paper, properties …

The light propagation in the medium normally experiences diffraction, dispersion, and
scattering. Studying the light propagation is a century-old problem as the photons may …

Bessel beams (BBs) have gained prominence thanks to their diffraction-free propagation
and self-healing properties. These beams are conventionally generated using different …

An optical trap forms a restoring optical force field to immobilize and manipulate tiny objects.
A fiber optical trap is capable of establishing the restoring optical force field using one or a …

We propose and experimentally demonstrate a fiber-based Bessel optical trap for the
simultaneous trapping of both high-refractive-index particle and a low-refractive-index …

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 …

Diffraction is a natural phenomenon, which occurs when waves propagate or encounter an
obstacle. Diffraction is also a fundamental aspect of modern optics: all imaging systems are …

Novel diffractive elements are presented to produce zero-order Bessel beams in the
terahertz (THz) band. First, diffractive elements are designed as phase plates to change the …

We report a new method to optically manipulate a single dielectric particle along closed-loop
polygonal trajectories by crossing a suite of all-fiber Bessel-like beams within a single water …

We present a novel and efficient approach to generating Bessel-like beams through
fabricating self-growing polymer microtips at the facet of single-mode fibers. To produce …
