dc.description.abstractMaterial response relevant to volume holographic storage for photorefractive crystals (K₀.₅Na₀.₅)₀.₂(Sr₀.₇₅Ba₀.₂₅)₀.₉Nb₂O₆:Cu (KNSBN:Cu) and LiNbO₃:Fe was studied in the near-infrared region. The dark decay time for KNSBN:Cu was measured to be on the order of 10⁶ s. The light-induced erasure time at the 1 mW/cm² read beam intensity can be ≳1000 h for both KNSBN:Cu and LiNbO₃:Fe. Read beam diffraction efficiencies of 28.7% for KNSBN:Cu and 50% for LiNbO₃:Fe were obtained at 706 nm when the refractive index grating was written at 706 nm. The decay rate of the refractive index grating with an extraordinary-wave read beam is about 3.6 times smaller than that with an ordinary-wave read beam for KNSBN:Cu. The results show that near-infrared light can be used to read holograms in the photorefractive volume holographic storage application.
