✦ Synopsis

We establish a system of difference-differential equations describing the diffraction of light by two mutually perpendicular supersonic waves. When the two supersonics have intensities of the same order of magnitude, we prove that the integration of these equations is reduced to the integration of two systems which are of the Raman-Nath type for the diffraction by one ultrasonic wave x). If the two ultrasonics have very different intensities, the equation becomes rather complicated. In this case it is still possible to reduce their integration to that of a system of the Raman-Nath type and to a more complicated one. Approximate solutions shall be established in a following paper.
