Research on spatially structured light has seen an explosion in activity over the past
decades, powered by technological advances for generating such light and driven by …

In 1832 Hamilton predicted that a collimated light beam propagating through a biaxial crystal
parallel to one of its optical axes refracts as a slanted cone within the crystal and emerges as …

Vector beams, beams with a non-uniform state of polarization, have become an
indispensable tool in many areas of science and technology. Harnessing topological light …

Nowadays, the well-known cylindrical vector beams (CVBs)–the axially symmetric beam
solution to the full-vector electromagnetic wave equation–are widely used for advanced …

We investigate theoretically the generation of extreme-ultraviolet (EUV) beams carrying
fractional orbital angular momentum. To this end, we drive high-order harmonic generation …

The use of structured ultrashort pulses with coupled spatiotemporal properties is emerging
as a key tool for ultrafast manipulation. Ultrafast vector beams are opening exciting …

Laser beams with a near uniform intensity profile, such as flat-top and super-Gaussian
beams, have found many applications, particularly in laser materials processing …

Polarization of a light beam is traditionally studied under the hypothesis that the state of
polarization is uniform across the transverse section of the beam. In such a case, if the …

A simple optical system is proposed to generate full-Poincaré beams (FPBs), ie beams
presenting all possible states of (total) polarization across their transverse section. The …

Functionalized Guar gum (GG) on the surface of iron oxide (Fe 3 O 4) nanoparticles was
synthesized via conventional co-precipitation method. The nanocomposite was …
