DOI: 10.1103/physreva.95.043836
Abstract: Iso-variance-matrix Laguerre-Gaussian superpositions corresponding to fundamental Laguerre-Gaussian modes are constructed and propagated numerically through atmospheric turbulence. The fact that these superpositions are iso-variance-matrix with the corresponding fundamental Laguerre-Gaussian mode ensures that both the superposition and… read more here.
