摘要：

We have demonstrated nonvolatile holographic storage with two-photon, two-step recording in nominally pure lithium niobate. An energy level slightly below the conduction band with lifetime 10-100 ms was found to be the intermediate state in the two-step electron ionization. The long lifetime allowed the use of cw lasers with moderate intensity at near infrared wavelengths. Nonvolatile readout of volume holographic images stored at near infrared wavelength was demonstrated.
