Ce:Cu:BSO crystal co-doped with CeO2 and CuO has been grown by the Czochralski method. The lattice constants, absorption spectrum, exponential gain coefficient, diffraction efficiency and respond time are measured. The lattice constants of Ce:Cu:BSO crystal are always larger than that of BSO crystal. Due to Ce and Cu ionic radii are larger than that of Bi3+ and Si4+, the lattice constants of doped crystal are larger than that of BSO crystal, thus make the absorption edge shift to the longer wavelength spectral range. The results indicate that the photorefraction of Ce:Cu:BSO crystal improves and the exponential gain coefficient and diffraction efficiency of Ce:Cu:BSO crystal improves two times compared with that of undoped BSO crystal. Furthermore, the photorefractive effect and the holographic storage effect of Ce:Cu:BSO crystal is better than that of undoped BSO crystal.
