Abstract-In this work, a novel family of Finite Airy array beams have been produced by an optical Airy transform system illuminated by Gaussian Array beams. Based on the generalized HuygensFresnel integral, an analytical expression is developed to describe the pattern properties of the beam generated at the output plan of the optical system. The well-known Finite Airy beam generated from the fundamental Gaussian beam using an optical Airy transform system is deduced, here, as a particular case of the main result of the actual study. Numerical calculations are performed to show the possibility to create a multitude of Finite Airy array beams with controllable parameters depending on the number of beamlets, the distance between the adjacent modules and the positions and orientations of the beamlets.

Using a recently proposed model for the refractive index fluctuations in oceanic turbulence, optical beam propagation through seawater is explored. The model provides an accurate depiction of the ocean through the inclusion of both temperature and salinity fluctuations to the refractive index. Several important statistical characteristics are explored including spatial coherence radius, angle-of-arrival fluctuations, and beam wander. Theoretical values of these parameters are found based on weak fluctuation theory using the Rytov method. The results presented serve as a foundation for the study of optical beam propagation in oceanic turbulence, which may provide an important support for further researches in applications for underwater communicating, imaging, and sensing systems.

“…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.
