Superior real-time holographic storage properties in doped potassium sodium strontium barium niobate crystal

Abstract

We demonstrate superior holographic storage performance in a cobalt doped potassium sodium strontium barium niobate (Co:KNSBN) crystal that possesses a fast response time of 1.4 ms, a large photorefractive sensitivity of $13\times {10}^{-3}\mathrm{cm}{}^3\mathrm{J}{}^{-1}$ under a total writing intensity of 1 $\mathrm{W}/\mathrm{cm}{}^2$, and high spatial resolution of 45 line pairs/mm. Reconstructed images with high fidelity have been obtained in real-time holographic storage. The dynamic properties of the index grating, the dependence of response time on writing intensity, and the dark decay of diffraction signal with increased writing intensity indicate that two species and shallow traps exist in Co:KNSBN crystal.
