Volume holographic recording of complex images with a double phase-conjugation mirror in a fiberlike Bi12TiO20 single crystal, mutually pumped by two separate He–Ne lasers, is experimentally demonstrated. Complex images can be stored and reconstructed by use of even a partial input image. The advantages of the small-cross-section, light-confining photorefractive sample in comparison with bulk crystal are a wider spatial bandwidth of recorded images and the possibility of recording holograms by application of smaller ac voltages.
