Adaptive phase correction of vortex lasers beams in a turbulent atmosphere

P. A. Konyaev, V. P. Lukin Institute of Atmospheric Optics, Siberian Branch of the Russian Academy of Science, Tomsk Abstract: A theoretical possibility of correcting amplitude–phase distortions of Laguerre–Gaussian (LG) laser beams on atmospheric paths is studied by computer simulation. Use is made of a dynamic adaptive correction scheme based on the principle of phase… Read More »
