How electrically induced elliptical polarization of sound affects the acoustooptic interaction in LiTaO3

摘要

This paper presents the results of an experimental study of how an electric field affects the position of the plane of polarization Of a transverse elastic wave and the acoustooptical interaction in a lithium tantalate crystal. It is established that an electric field of 1 kV/cm rotates the plane of polarization of a sound wave with frequency 580 MHz passing thought 1 cm of a crystal by 2.5 degrees. The nonlinearity parameter is evaluated at gamma(E)=4.3 X 10(-11) m/V. (C) 2005 Optical Society of America.
