ABSTRACT
There is a problem of sustainable wireless communication through atmospheric turbulence. To address this problem, it is necessary to find laser beams which are resistant to the atmosphere distortions. The relevance of the studied problems for physics is due to the fact that theoretical results were obtained by using the analytically derived new solutions of the Helmholtz equation and its paraxial approximation, and therefore these results are universal for wave theories that occur in different areas of physics. Theoretically, there is an infinite number of orthogonal states with different orbital angular momentum (OAM). Therefore, spatial modes of light can potentially carry a vast amount of information, making them promising candidates for both classical and quantum communication. Along with fiber and wireless communications, light fields with the OAM are used for optical trapping of microobjects. The problem of simulation of manipulating microscopic objects by laser radiation was considered in many ways.
