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 last decade witnessed considerable progress in the development of laser
ablation/ionisation time-of-flight mass spectrometry (LI-TOFMS). The improvement of both …

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

During the process of Bessel beam generation in free space, spatiotemporal optical wave-
packets with tunable group velocities and accelerations can be created by deforming pulse …

Abstract Three-dimensional (3-D) light solitons in space–time, referred to as light bullets,
have many novel properties and wide applications. Here we theoretically show how the …

Bessel beams have a wide range of applications in optical communications because their
non-diffractive properties do not depend on the amplitude and phase distribution in the …

We experimentally generate n= 0 Bessel beams via higher-order cladding mode excitation
with a long period fiber grating. Our method allows> 99% conversion efficiency, wide or …

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 …

A Bessel-like beam was generated in a novel all-fiber integrated structure. A concentric ring
intensity pattern was achieved by the multimode interference along the coreless silica fiber …
