Abstract :
Summary form only given. Holographic gratings with high diffraction efficiency (>50%) can be recorded in YAlO/sub 3/:Mn with green or blue laser beams. The storage time extrapolated to room temperature is much greater than ten years. Gratings can be erased by heating the crystal to about 270/spl deg/C. These properties in combination with the high optical quality of the crystal give promise to this material for use in holographic data storage.
