Science Newsletter of the Faculty fo Physics
This is a new bulletin, which, as we hope, will bring fresh, updated information on scientific news, research activities, and related events in the life of our department to our staff members, undegraduate and graduate students, postdocs, collaborators and partners. We greatly hope that this Science Newsletter will help us to find new partners in research and shorten the way from fundamental research to applications and innovations, from our fundamental discoveries to their successful implementations in not too distant future.
XIV National School-Seminar "Wave phenomena in inhomogeneous media"
The conference papers from the School-Seminar «Waves-2014» will be submitted for publishing in the Memoirs of the Faculty of Physics journal.

Acousto-optic effect in media with strong acoustic anisotropy
V.I. Balakshy, A.S. Voloshin
Department of Oscillation Physics, Faculty of Physics, M.V.Lomonosov Moscow State University. Moscow 119991, Russia.Results of theoretical and experimental investigation of acoustic beam walk-off influence on acousto-optic characteristics in a paratellurite single crystal are presented. Variants of isotropic and anisotropic diffraction are analyzed. Angular and frequency characteristics of acousto-optic interaction are calculated on the basis of modified Raman–Nath equations in wide ranges of Bragg angles and acoustic frequencies. It is established that the acoustic walk-off can change essentially the width of acousto-optic range. Therefore this effect should be taken into consideration at designing acousto-optic instruments. Experimental verification of the numerical calculations is fulfilled with an acousto-optic cell made of paratellurite cut.
