“…In practice, the beam array can achieve high power, and can be Photonics 2023, 10, 551 2 of 10 composed of off-axis beams [28,29]. The radial intensity distribution of the beam array can be obtained by radially phase-locked PCBs [30][31][32]. The splitting properties of HGCSM are very interesting.…”

The descriptions of a radially phased-locked Hermite–Gaussian correlated beam array are introduced, the equation of this beam array in oceanic turbulence is derived, and the intensity profiles of this beam array are shown and analyzed. The results imply that the evolutions of the sub-beam of this beam array in free space are the same as the Hermite–Gaussian correlated beam, while the intensity of this beam array can be adjusted by controlling the initial beam radius R and the coherence length. The intensity profiles of this beam array in free space have multiple spots during propagation, while the same beam array in oceanic turbulence can become a beam spot due to the influences of R and oceanic turbulence. The beam array with smaller coherence length in oceanic turbulence retains the splitting properties better during propagation.
