“…All allowable paths can be divided into a few clusters, for example, when P, N < 5, the final state is {l, 0, 0, 0, 0}, the cluster is composed of (l); (1,4,4,5,5). Every cluster is also divided into a few paths, it is easy to determine the number of paths.…”

A Feynman diagram theory for acousto-optic (AO) interaction is established, which supplies a general method to calculate the scattering amplitudes and intensities for both single frequency and multifrequency AO interactions. The method is based on counting the number of allowable Feynman diagrams. Based on this, a complete solution for the scattering amplitudes and intensities an be obtained for any kind of AO interactions, any number of acoustic frequencies, and any final states. A geometrical representation for this Feynman diagram theory of AO interaction is set up too. The theory is also verified by comparing with the experiments.
