Rotation of the incident optical beam in Te02 allows selection of the tangential AO interaction to achieve higher efficiency-bandwidth product. This interaction mode results in improved diffraction efficiency by having a longer interaction length, an increase in the two-tone dynamic range, and allows for the use of linear laser polarization. A detailed analysis shows the distinction between the Z axis incident wave and the rotated incident wave in phase mismatch conditions and the efficiency bandwidth relationship. Two devices were fabricated with the following characteristics: aperture time of 70 microseconds with 30 MHz bandwidth; and aperture time of 50 microseconds with 40 MHz bandwidth. A brief result of the phase mismatch analysis, design of the devices, and measurements of the performance compared against theory are presented.
