Spiral fractional vortex beams
Optics Express, 2023 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
Results in Physics, 2022 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 ...

Peculiar rotation of electron vortex beams [PDF]
Ultramicroscopy, 2015 Standard electron optics predicts Larmor image rotation in the magnetic lens field of a TEM. Introducing the possibility to produce electron vortex beams with quantized orbital angular momentum brought up the question of their rotational dynamics in the presence of a magnetic field. Recently, it has been shown that electron vortex beams can be prepared
