In advanced telecommunication systems, ensuring high reliability of information transmission is one of the main tasks, which is achieved by the accuracy of the spatial aiming of the laser beam, the width of which is commensurate with the aiming error. In this case, in practice, the transmitting laser means generate and emit not one, but several transverse modes, which affects the quality of signal reception. Purpose is investigation of the influence of multimode and precision control of the spatial position of the laser beam on the quality of signal reception and the choice of rational parameters of laser radiation, taking into account the accuracy characteristics of the guidance system.

With regard to multimode radiation using the method of functional transformation of random variables and the properties of the Laplace transformation, the density distribution of the radiation intensity of the transmitting laser device in the region of the receiving system was substantiated, with the use of which the signal reception efficiency was studied depending on the pointing accuracy of the multimode laser beam and the character the initial distribution of its intensity in the cross section.

The practical significance of the research carried out is due to the need to improve the quality of communication in telecommunication systems and lies in the possibility of their application in the construction of advanced control systems and data transmission.
