Abstract
The phased array transducer and birefringent Bragg interaction provide a unique combination of features not available with the usual acoustical or optical rotation schemes in slow shear TeO2. A general theory for phased array Bragg interaction in a birefringent medium is presented. A 50 MHz bandwidth slow shear TeO2 Bragg cell was constructed using this theory. Excellent match between the designed and observed frequency band was obtained. As a result of the strong anisotropy of the acoustic velocity, we were able to reduce the intermodulation products by removing the negative first-order acoustic beam from the optical interaction region. The limitation in performance imposed by previous slow shear TeO2 designs using either optical or acoustical rotation are eliminated.
