Thirty years ago, Coullet et al. proposed that a special optical field exists in laser cavities
bearing some analogy with the superfluid vortex. Since then, optical vortices have been …

Low-intensity light beams carrying orbital angular momentum (OAM), commonly known as
vortex beams, have garnered significant attention due to promising applications in areas …

We present acoustic modeling, measurements, and interpretation of the angular momentum
carried in an ultrasonic vortex beam that is obliquely reflected off a flat water-air interface …

We present a new magnetic field generation mechanism in underdense plasmas driven by
the beating of two, copropagating, Laguerre-Gaussian orbital angular momentum laser …

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

When a high power laser beam irradiates a small aperture on a solid foil target, the strong
laser field drives surface plasma oscillation at the periphery of this aperture, which acts as a …

It is well known that light can possess spin angular momentum (SAM) and orbital angular
momentum (OAM) in the longitudinal direction. Interesting novel light with transverse SAM or …

When a circularly polarized (CP) Gaussian beam normally irradiates a solid plasma target,
the spin angular momentum of the CP beam transforms into the orbital angular momentum …

This paper is devoted to the study of vortex beam transmission from an adjustable
magnetized plasma-ferrite structure with negative refraction index. We use the angular …

Spatiotemporal optical vortex (STOV) pulses carrying purely transverse intrinsic orbital
angular momentum (TOAM) are attracting increasing attention because the TOAM provides …
