Abstract
Acousto-optic device are used in various signal processing systems and laser radiation controlling systems. These systems allow the wideband signals processing in real-time and high-speed laser beam scanning. In this paper, dependences of electromechanical coupling coefficient for different slices of a lithium niobate crystals are calculated. They illustrate the validity of selecting the appropriate cut for the piezoelectric transducer for the excitation of longitudinal waves and shear waves in acousto-optic cells. Also, these dependences determine the criteria for the accuracy of the technological requirements for the piezoelectric plate transducers constructing.
