Abstract
An opto-optical light deflector/modulator has means for providing first and second coherent wave fronts of wavelength (.lambda..sub.0) to travel in a transparent optical active medium to produce an optically generated standing wave that induces a periodic refractive index variation in the medium suitable for diffraction purposes. The device also includes means for providing a third wavefront (.lambda..sub.1) to travel in said medium which is diffracted by the periodic refractive index variation induced by the first and second wavefronts.
