TL;DR: The numerical results show that the M(2)- factor of a DHB in turbulent atmosphere increases on propagation, which is much different from its invariant properties in free-space, and is mainly determined by the parameters of the beam and the atmosphere.

TL;DR: In this paper, an explicit expression for the scintillation index of a multi-Gaussian Schell-model (MGSM) beam in weakly or extremely strong turbulent atmosphere is derived with the help of a tensor method.

TL;DR: The propagation of an elegant Hermite-Gaussian beam (EHGB) in turbulent atmosphere is investigated, and it is found that the propagation properties of EHGBs and SHGBs are much different from their properties in free space, and the EH GB with higher orders are less affected by the turbulence.

TL;DR: Analytical formulas for the average intensity and the beam width of the elegant Laguerre-Gaussian beam in non-Kolmogorov turbulence have been derived based on the extended Huygens-Fresnel principle and reveal that the ELGB converts to Gaussian form quicker for smaller values of beam order and for smaller wavelengths.

TL;DR: In this article, the average intensity and spreading properties of an elegant Laguerre-Gaussian beam (ELGB) in a turbulent atmosphere were investigated in detail, and the results indicated that the propagation properties of the ELGB in turbulent atmosphere are much different from its properties in free space, and are closely related to its beam parameters and the structure constant of the atmospheric turbulence.
