Abstract

We have observed quasinondestructive holographic storage with a continuous-wave laser at λ=532 nm in near-stoichiometric LiNbO₃ doped with Tb and Fe. This crystal showed an exceptionally long grating decay time and also exhibited a fast color change upon exposure to ultraviolet (UV) light. It was demonstrated that the grating recorded from the UV-exposed, colored state can be continuously read out over 9 h at a reading intensity as high as 8 mW/cm². In addition, the written grating could be easily erased with UV illumination which returned the crystal back to the original colored state.
