Works on laser physics and optics, the dynamics of nonlinear systems, the physics of nanoscale structures. He proposed and developed the method of selection of laser frequencies, based on the difference in saturation parameters of media. He discovered qualitatively new polarization phenomena in gas lasers in a magnetic field. He established the role of stimulated Raman resonance scattering processes in an active medium in the formation of laser characteristics in a magnetic field. He proposed and developed resonant phase-polarization methods of quantum electronics and laser spectroscopy, showed the effectiveness of these methods for frequency selection in various types of lasers and for increasing the sensitivity of intracavity laser spectroscopy. He created the polarization dynamics of nonlinear systems and showed, in particular, that the formation time of the polarization of the generated radiation is a characteristic constant of a laser, which in certain cases has a significant effect on the dynamics. He determined and studied the phenomena of spontaneous breaking of polarization (mirror) symmetry in lasers, up to obtaining complete chiral purity. I found new active media based on crystals with impurity and own radiation color centers. He proposed film structures with a spatially organized network of nanoscale crystals and studied their properties..

Author of about 250 scientific papers, incl. 2 monographs, reference book, 25 inventions.

State Prize of the Republic of Belarus in 1996 for the series of works "Phenomena of anisotropy in lasers and principles of polarization laser spectroscopy". Prize of the National Academy of Sciences of Belarus and the Siberian Branch of the Russian Academy of Sciences named after Academician V.A. Koptyug in 1999 for a series of works "High-resolution laser spectroscopy and its fundamental applications".

Awarded with the Badge of Honor (1981), of Francisk Skaryna (1998), with a medal.
