| Abstract: | By using the acoutic-optic, the approximate analytical expression of small angle Bragg diffraction is obtained. The intensity of diffraction light with different acoustical power and drive frequency are measured. The influence of various factors on diffraction efficiency are discussed. The results may provide foundation for the application of both the acoustic-optic experiment and corresponding theory. |
