Computer simulation of scalar vortex and annular beams LG0L beams in time-varying random inhomogeneous media

Computer modeling of annular and vortex Laguerre-Gaussian beams LG_0L propagation in random inhomogeneous media using the dynamic time-varying algorithm of media evolution is presented. The temporal power spectrum of vortex beam LG_0L has been investigated by numerical simulation of propagation through atmospheric turbulence. The split-step Fourier method was used for solving scalar wave equation for a randomly inhomogeneous medium with a power-law Kolmogorov spectrum.
