Abstract
In a previous article, a plane-wave model for strong acousto-optic interaction was developed. In this earlier model, any particular order is contributed to by a multiple-scattering process, involving all other orders. The model involves “direct” scattering paths and “feedback” paths and, in general, provides an implicit solution. The present article describes a variant of this multiple-scattering formalism, in which feedback paths and direct paths are combined so that all orders are explicitly derivable from the incident-light field. We show the usefulness and validity of this approach by rigorously deriving the well-known expressions for Raman-Nath and Bragg diffraction.
