Spreading properties of multi-Gaussian Schell-model beam array in maritime atmospheric turbulence

Based on the extended Huygens-Fresnel principle, the propagation equations of rectangular multi-Gaussian Schell-model (MGSM) beam array generated by the multi-Gaussian Schell-model source in maritime atmospheric turbulence are derived. The evolutions and effective beam widths of MGSM beam array propagating in maritime atmospheric turbulence are analyzed by using numerical examples. The obtained results are beneficial to the practical application of MGSM beam array in maritime atmosphere.
