Abstract:
This paper describes the results of the investigation of a random flight of a center of gravity of a vortex laser beam, propagating in a medium with heterogeneities of a dielectric constant. The beam is a circular mode of the Laguerre–Gaussian beam LG01. We estimated the effect of turbulent conditions of propagation, diffraction parameters, and azimuth index (topological charge) of the beam on the magnitude of variance of shifts of its center of gravity. The effect of a gyroscope has been detected, which lies in the fact that in the modes of weak and moderate turbulence the random shifts of center of gravity of the vortex laser beam are found to be the less, the greater is the topological charge of the beam optical vortex.
