【Abstract】 A set of coupled wave equations for multiple dimensional acoustooptic diffraction with multiple acoustic waves along different directions is put forward and its solutions are derived. The characteristics of the diffraction efficiency, compression, cross modulation, and intermodulation intensities are analysed theoretically. The theoretical results are supported by experimental measurements through our new multiple dimensional acoustooptic devices.更多还原
