<p>Medium for use as a reversible optical information carrier consists of an (in)organic substance with (micro) crystalline structure, doped with Sc ions. This medium has great long-term stability and adequate change in extinction coefft. is obtd. by simple doping with rare earth. Light of the same wavelength can be used for storage and reading, so that it is possible to store thick holograms. The medium can be formed from monocrystals or thin layers, which are doped during or after mfr.</p> |
