ABSTRACT:
An optical device for storing a coherent image in a multimode cavity makes use of two interaction media in which photoinduced phase gratings are recorded. By way of example, these media are photorefractive media. A first wave designated as an object wave travels through the cavity and interferes in each of these two media with a pumping wave in order to permit energy transfer from the pumping wave to the first wave.
