“…Importantly, the existed results show that different OAM beams have different propagation properties in the underwater environment. For example, Huang et al investigated the propagation of Gaussian Schell-model vortex beams through oceanic turbulence, and showed that both position and number of coherent vortices were changed with the increasing of propagation distance [1]. The propagation of a partially coherent cylindrical vector Laguerre-Gaussian(LG) beam passing through oceanic turbulence was investigated in [4], and the results showed that the smaller the initial coherence length of beam was, the larger the influence of ocean turbulence was.…”

With Rytov approximation theory, we derive the analytic expression of detection probability of Airy vortex beam carrying orbital angular momentum (OAM) through an anisotropic weak oceanic turbulence. We investigate the influences of turbulence parameters and beam parameters on the propagation properties of Airy-OAM beam. The numerical simulation results show that the anisotropic oceanic turbulence with a lower dissipation rate of temperature variance, smaller ratio of temperature and salinity contributions to the refractive index spectrum, higher dissipation rate of kinetic energy per unit mass of fluid, bigger inner scale factor, larger anisotropic coefficient causes the larger detection probability of Airy-OAM beam. Moreover, the Airy-OAM beam with a smaller topological charge, larger main ring radius and longer wavelength, has strong resistance to oceanic turbulent interference. Additionally, the detection probability decreases with the increase of receiving aperture size. In comparison with Laguerre-Gaussian-OAM beam, Airy-OAM beam has more anti-interference to turbulence when its topological charge is larger than 5 due to its non-diffraction and self-healing characteristics. The results are useful for underwater optical communication link using Airy-OAM beam.

“…It is already well-known that the optical turbulence in underwater environments, such as in oceanic environments, is mainly induced by temperature and salinity fluctuations. This turbulence has severely degraded the communication quality of the OAM-based UWOC system 16–19 . For example, in 16 there is a theoretical study of the influence of temperature and salinity fluctuations on the average intensity of Gaussian Schell-model vortex beams in the turbulent ocean that showed that partially coherent beams have more robust turbulence resistance than fully coherent ones.…”

In this paper, we report on experimental demonstration of the propagation and self-healing property of Bessel-Gaussian (BG) beam carrying orbital angular momentum (OAM) in an underwater environment. Especially, the effects of topological charge, temperature gradient, and salinity on the transmission and self-reconstruction of BG beam in underwater turbulence are analyzed. The results show that the detection probabilities both for propagation and self-healing greatly decrease with temperature gradient, and gradually decrease with salinity. BG beam has a self-healing property in the underwater environment when the obstruction is quite small. The detection probability greatly decreases with obstruction size, while it gradually decreases with salinity fluctuations for different obstruction sizes. For the same blockage ratio, the smaller topological charge of BG beam is, the better self-healing characteristics the BG beam has.

“…With the application of laser technology in underwater, the evolution properties of laser beams propagating in oceanic turbulence have been investigated. In recent years, the propagation properties of various laser beams in oceanic turbulence have been illustrated and analyzed, including the scintillation index of laser beam [18], mutual coherence function of laser beam [19], astigmatic stochastic electromagnetic beam [20], partially coherent flat-topped vortex hollow beam [21], partially coherent annular beam [22], Gaussian Schell-model vortex beam [23], stochastic electromagnetic vortex beam [24], flat-topped vortex hollow beam [25], partially coherent Hermite-Gaussian linear array beam [26], partially coherent four-petal Gaussian vortex beam [27], Gaussian array beam [28][29][30], partially coherent cylindrical vector beam [31], chirped Gaussian pulsed beam [32], Lorentz beam [33] and partially coherent four-petal Gaussian beam [34]. To the best of our knowledge, there has been no report on the propagation analysis of partially coherent Lorentz beams propagating in oceanic turbulence.…”

Partially coherent Lorentz beams have been introduced to describe the output of the diode laser, which have been investigated due to the special spreading properties. The analytical expressions of partially coherent Lorentz beam propagating in oceanic turbulence are derived. Using the derived equations, the average intensity distributions of partially coherent Lorentz beam are analyzed and discussed. It is shown that the partially coherent Lorentz beam with smaller coherence length will evolve into the Gaussian-like beam faster, and the beam propagation in oceanic turbulence will spread faster with increasing strength of oceanic turbulence. The results have potential application in underwater optical communications and sensing.
