Aa. Kamshilin et al., HOLOGRAPHIC RECORDING OF COMPLEX IMAGES BY DOUBLE-PHASE CONJUGATION IN BI12TIO20 FIBERLIKE CRYSTAL, Optics letters, 19(12), 1994, pp. 907-909
Volume holographic recording of complex images with a double phase-con
jugation mirror in a fiberlike Bi12TiO20 single crystal, mutually pump
ed by two separate He-Ne lasers, is experimentally demonstrated. Compl
ex images can be stored and reconstructed by use of even a partial inp
ut image. The advantages of the small-cross-section, light-confining p
hotorefractive sample in comparison with bulk crystal are a wider spat
ial bandwidth of recorded images and the possibility of recording holo
grams by application of smaller ac voltages.
