Abrupt autofocusing performance of a circular Airyprime beam with vortex pairs
Results in Physics, 2023 Abrupt autofocusing performance of a circular Airyprime beam (CAPB) with vortex pairs propagating in free space is investigated. Here the vortex pairs are off-axis by default.

Experimental generation of arbitrary abruptly autofusing Circular Airy Gaussian vortex vector beams [PDF]
Scientific Reports, 2022 Complex vector modes represent a general state of light nonseparable in their spatial and polarization degrees of freedom, which have inspired a wide variety of novel applications and phenomena, such as their unexpected propagation behaviour. For example,

Changing the trajectory of Airy beam sets with spatial carriers
Компьютерная оптика, 2022 In this paper, we study a change in the propagation trajectory of a set of autofocusing laser beams using a fractional Fourier transform. Clusters of displaced bounded Airy-Gaussian beams supplemented by a phase function that deflects the beam similarly ...
