Fe:LiNbO3 crystal is a kind of common used photorefractive materials with large electrooptic (E - O) coefficients, high photorefractive sensitivity and diffraction efficiency. Compared with BaTiO3 series photorefractive crystals, it has some outstanding advantages such as easy operation and storage, low cost and large size availability, which make it more suitable for volume fabrication and practical devices. Therefore, Fe:LiNbO3 crystal has a wide range applications: Holographic Storage; Bragg Grating, Dynamic Holography; Optical Memories; Optical Phase Conjugation and Neutral Networks. All the Fe:LiNbO3 crystal devices from us are completely poled and strain & scatter free. They are of low variation of refractive indices and high extinction ratio. Special processing techniques are implemented to meet OEM and R&D requirements.
