Abstract

In this paper, the propagation characteristics of a ring Airy vortex beam (RAVB) in slant atmospheric turbulence are studied. The effects of some key parameters, such as the truncation factor, the zenith angle, and the propagation distance, on the propagation characteristics of RAVB are analyzed. The results show that the beam quality becomes worse with an increase in the propagation distance, zenith angle, and truncation factor. When the propagation distance exceeds 3 km in turbulence, the value of the aperture-averaged scintillation index will reach the peak value. On the other hand, the mean signal-to-noise ratio of this beam will be affected by the propagation distance. The beam quality can be improved by increasing the topological charges. When the truncation factor is 0.1, RAVB performs best when the distance is long.
