Аннотация: Propagation and reflection of plane elastic waves in the acousto-optic crystal tellurium dioxide is examined in the presentation. The reflection of the waves from a free and flat boundary separating the paratellurite crystal and the vacuum is investigated in the (001) and the (110) planes of TeO2 in the case of glancing and inclined acoustic incidence on the boundary. The analysis shows that as much two elastic waves may be reflected from the crystal surface. Energy flow of one of the reflected waves propagates in a quasi-back direction with respect to the incident energy flow unusually reflected wave may be close to a unit in a wide variety of crystal cuts. Possible applications of the examined phenomena in acousto-optic devices are discussed in the presentation.
