Propagation of Partially Coherent Flat-Topped Vortex Hollow Beams in Anisotropic Turbulent Plasma
The propagation properties of partially coherent circular flat-topped (FT) vortex hollow/nonvortex beams are studied in anisotropic turbulent plasma. The analytical expression of the optical intensity of these beams is obtained by employing the extended ...

Spiral fractional vortex beams
A new type of spatially structured light field carrying orbital angular momentum (OAM) mode with any non-integer topological order, referred to as the spiral fractional vortex beam, is demonstrated using the spiral transformation. Such beams have a spiral intensity distribution and a phase discontinuity in the radial direction, which is completely ...

Generation and characteristics of an Airy vortex beam from the anomalous vortex beam
Hybrid beams have evoked a long-running research upsurge due to its unique properties and extensive application. In this paper, we propose a novel method to generate a kind of hybrid Airy vortex beam (AiVB) with orbital angular momentum (OAM) by imposing a phase modulation on an anomalous vortex beam (AVB), which hybrid AiVB possesses dual ...

Optical vortices generically arise when optical beams are combined. Recently, we reported how several laser beams containing optical vortices could be combined to form optical vortex loops, links and knots embedded in a light beam (Leach et al 2004 ...

Research on Blind Area Suppression Technology for Vortex Beam Detection [PDF]
To address the problem of far-target detection blind areas caused by the dark hollow regions in the propagation direction of vortex beams, a method based on the coherent synthesis of vortex superposition using a ring-beam array is proposed.
