摘要：

Spectroscopic properties of new aluminum oxide crystals for volumetric optical data storage are investigated. Magnesium impurity and double oxygen vacancy defects are responsible for the main optical properties of the new material. Sequential two-photon absorption and ionization of color centers followed by capture of a free electron on a deep trap is a suggested mechanism for writing information. One-photon absorption and non-destructive readout using reconstruction of recorded holograms or a confocal fluorescence detection scheme are proposed.
