APPLICATION OF IONIC CRYSTALS WITH ANISOTROPIC DOPED COLORING CENTERS FOR OPTICAL STOROGE DEVICES
Photoactive anisotropic color centers of various types in ionic crystals may be oriented by the polarized light as well as transformed into other types of oriented anisotropic centers. This phenomenon is supposed to be used in designing an optical memory device. The possibility for the choice of different combinations of crystals and impurities, types of centers and conditions for their formation allows wide variation of the optical and thermal properties of these systems and makes it possible to devise a memory devise with optimal characteristics. Different methods of recording and retrieval of information are considered, which are based on the anisotropy properties of photoactive centers in cubic ionic crystals.
