Abstract
A crystal holder for use with photorefractive crystals comprises a horizontal rotatable planar member on which is mounted a crystal, such that the axis of rotation of the planar member lies on a face of the crystal on which a beam of light impinges. In a preferred embodiment, the crystal may be moved such that the axis of rotation continues to lie on the face of the crystal over at least a substantial portion of the face. The crystal holders of this invention are useful, for example, in phase conjugate mirrors.
