Abstract

We have prepared several phase plates to observe phase conjugation by stimulated Brillouin scattering in carbon disulfide in the usual way. One of the plates was specially made, lightly ground by fine emery. Its spatial Fourier spectrum shows a very bright spot in the center of the speckle pattern, which means that the light beam that passed through this plate consisted of a strong plane wave component and many weak random components. This is different from the phase plate in phase conjugation by stimulated Brillouin scattering given in earlier papers,¹ but, using only this special plate, we have successfully obtained phase conjugation.
