BELY Vladimir Nikolaevich

Vladimir Nikolaevich Bely (b. 25.10.1947, v. Rafalov, Bragin district, Gomel region) - a scientist in the field of optics and laser physics. Corresponding Member (2014), Doctor of Physico-Mathematical Sciences (1992), Professor (1994). Honorary Doctor of the Gomel State University named after F. Skaryna (2009).

He developed a theory of laser beams with a complex spatial structure (Gaussian, Bessel, conical, Lagerr- and Bessel-Gaussian, Vortex and Singular, Quasi-Diffraction Speckle Fields, etc.) during their propagation and transformation in anisotropic, inhomogeneous and scattering media. Predicted and investigated a number of new optical effects (laser magnetorefraction, the effect of diffractionless diffusion of light beams in the vicinity of the special directions of biaxial crystals, spin-orbit coupling, the effect of self-tuning for phase matching, polarization-independent modulation). Theoretically substantiated and proposed new principles for controlling the parameters of laser radiation based on electro-acousto-optic interactions. He developed and created high-performance nonlinear-optical frequency converters, acousto-optical deflectors and laser radiation modulators. Established a new type of optical spatial solitons in photorefractive crystals. For the first time he investigated the features of the spin-orbit transformation of Bessel light beams in crystals. Predicted and researched a new type of quasi-non-diffractive surface plasmon polaritons, as well as light fields of a special type - quasi-non-diffraction multiplasmon. Developed original interferometric, speckleometric and tomographic methods and devices for laser diagnostics and non-destructive testing. On the basis of hyperbolic metamaterials, new configurations of flat lenses (the so-called super lenses) of the near and far fields have been proposed and implemented.

Leninsky Komsomol Prize of Belarus (1978) for the series of works “Study of the processes of laser radiation conversion and the development on its basis of sources of powerful coherent light with a smooth frequency tuning in the visible, ultraviolet and infrared ranges”. State Prize of the Republic of Belarus (2000) for the series of works “Research of nonlinear optical phenomena and creation on this basis of new highly efficient sources of laser radiation”.

Awarded with medals "For Military Valor" (1970), Francisk Skaryna (2006).
