Study of conservation of the topological charge of vortex beams transferring in a random media

The modelling of propagation of optical beam through the random media based of extended Huygens-Fresnel principle was considering. The correlation function of random media is Gaussian function. The objects of the study are Laguerre-Gaussian modes, because they represent vortex beams. The examples of modes transmission were provided. The topological charge… (More)
