Abstract
The distribution laws of fluctuations of the field amplitude and intensity of laser beams propagating through the atmosphere are studied based on numerical simulation. The calculations are performed for the beams having the orbital angular momentum (vortex beams) at different points of their cross section. The transformation of probability densities of fluctuations of the field amplitude and intensity of the beams is studied for the relative variance of intensity fluctuations (scintillation index) varying from unity to three. It is shown that if the scintillation index has the same values at different points of the beam, the probability density of intensity has the same form, whereas the probability density of the real and imaginary parts of the field amplitude can differ.
