Paper Abstract

In recent years, doped KLTN (K1-xLixTa1-yNbyO3) crystal in paraelectric state was reported to be a new type of holographic storage medium owning to its great promotion for diffraction efficiency, through quadratic electro-optical effect generated by external electrical field. In this paper, we describe the preparation method of the KLTN crystal in our laboratory and report our preliminary experimental research on electrically controllable holography in a KLTN: Cu crystal. It was found that the writing intensity and polarization of the readout beam affect the diffraction efficiency remarkably, and the voltage selectivity of holograms stored in the crystal was observed, which is potential to increase the storage capacity.
