Paper Abstract

Acousto-optic (AO) technology sprang up at the beginning of 1960s, after the naissance of laser. The electro-acoustic transducer is an important part of acousto-optic device (AOD), and quartz is an important crystal for making the transducer due to its good piezoelectric property. In this paper we calculated two kinds of acoustic velocities, non-strengthened acoustic velocities and strengthened acoustic velocities, for three kinds of acoustic modes, one longitudinal wave and two shear waves, in three coordinate planes of the quartz systematically using Christoffel equations. Then electromechanical coupling coefficients of every acoustic mode are calculated and curves of coefficients in three coordinate planes are pictured. Finally we determined the optimum cut direction of longitudinal wave and shear wave respectively. The results of this paper will play a directional role for the research of AOD.
