“…In comparison, Bessel-Gaussian beams outperform LG beams in resisting ocean turbulence, benefiting from their non-diffracting and self-repairing features [4] . Further, Lu et al [5] . 's work on the scintillation factor of elliptical vortex beams suggests they offer superior resistance to ocean turbulence over both Gaussian and traditional vortex beams .…”

In this study, we employ the distributed phase screen method to simulate the transmission of Autofocusing Airy beams (AAB) with a new kind of power-exponent-phase vortex (NPEPV) through oceanic conditions, including the effects on light intensity and scintillation. We observe that during the oceanic transmission of an AAB with NPEPV, the beam's main ring progressively divides into fan-shaped sections that match the number of topological charges, with the ring maintaining its integrity without splitting at higher power indices. Furthermore, the scintillation index for AAB with NPEPV decreases as the topological charge increases, up to 400 m. Beyond this distance, the beam structure is significantly disturbed and the relationship between scintillation index and topological charge becomes irregular. Additionally, a higher power index results in a smaller scintillation index slope over the transmission distance and smoother fluctuations in the scintillation factor. At the same transmission distance, a smaller girdle radius leads to a lower scintillation index for AABs with NPEPV.

“…However, unlike the terrestrial environment, the propagation characteristics of laser beams through maritime atmospheric turbulence exhibit some significant differences due to the combined effects of temperature and humidity fluctuations in the maritime atmosphere. Consequently, discussions regarding the propagation characteristics of laser beams through maritime atmospheric turbulence have been conducted [6][7][8][9][10][11][12][13][14][15][16]. However, most of the research studies have focused on the different types of laser beams, such as Gaussian beams and various vortex beams, with limited studies on vortex beam arrays.…”

This study employs the power spectrum inversion method to generate the phase screens of atmospheric turbulence over the sea, the theoretical model of the vortex beam array emitted by a focusing system through anisotropic non-Kolmogorov maritime atmospheric turbulence was built. The propagation characteristics of the vortex beam array were investigated theoretically and compared to those of the Gaussian beam array. The results show that the vortex beam array is less affected by turbulence and exhibits stronger resistance to the turbulence. On this basis, using the evaluation parameters including the relative beam width and the beam wander, the influences of various parameters of the vortex beam array and atmospheric turbulence, such as topological charge, beamlet width, number of beamlets, anisotropy factor, and power law, on its propagation characteristics through anisotropic non-Kolmogorov maritime atmospheric turbulence were studied extensively. The results can provide a useful reference for the applications of the vortex beam array in optical communication through the maritime atmosphere.
