Transformation of acoustic modes in acousto-optical devices
The results from studying previously unknown cases of the reflection of bulk acoustic waves in an acousto-optical paratellurite crystal with arbitrary incidence of an elastic wave on a free interface between the crystal and vacuum are presented. The incidence of waves at different angles in the XOY plane of the material is analyzed. New cases of the reflection of acoustic waves are considered and the efficiency of the transformation of energy from an incident elastic wave into the energy of reflected waves are investigated.
