OPTICAL DEVICE FOR REAL-TIME AMPLIFICATION OF THE RADIATION ENERGY OF A BEAM

摘要

An object beam and a reference beam incident on a photosensitive recording material interfere with each other to form a refractive-index strata grating. An energy transfer takes place between the reference beam and the object beam in the presence of a transverse electric field applied to the terminals of the material. A displacement of the interference fringes within the medium permits operation under optimum energy transfer conditions.
