Interest in the multiple facets of optical vortices has flourished in the last three decades. This
review examines the basic research and applications of the interplay between optical …

Chiral interactions are prevalent in nature, driving a variety of biochemical processes.
Discerning the two non-superimposable mirror images of a chiral molecule, known as …

We demonstrate an alternative approach for generating zeroth-and first-order long range
non-diffracting Gauss–Bessel beams (GBBs). Starting from a Gaussian beam, the key point …

A novel chiroptical sensing technique was recently introduced that utilized the helical phase
of the structured light as a chiral reagent instead of polarization of light to differentiate …

We studied the evolution of the incubation effect during fs-laser micromachining of gallium
nitride films with the number of laser pulses applied per sample surface area. The damage …

Beam shaping has been widely used in laser processing. Compared with Bessel beam,
Bessel-like beam has unique advantages of fabricating high-aspect-ratio holes due to its …

In this paper, we study the characteristics of the supercontinuum (SC) induced by the
filamentation of two typical vortex beams (ie, Laguerre-Gaussian (LG) and Bessel-Gaussian …

We introduce the optical vortex beam into simultaneous spatial and temporal focusing
(SSTF) technique, and theoretically and experimentally demonstrate the local control of …

We report a method for measuring spot size and focusing conditions of the femtosecond (fs)
excitation laser in situ at the specimen location in 4D ultrafast electron microscopy (UEM) …

Fluorescence emission is a typical nonlinear phenomenon occurring during the
femtosecond laser filamentation in air. The characteristics of nitrogen fluorescence emission …
