In the paper Ce:Cu:BSO crystal has been grown by Czochralski method for the first time with doping CeO2 and CuO into BSO(Bi12SiO20) crystal. The exponential gain coefficient and respond time of Ce:Cu:BSO crystal are measured by two-wave-coupling technology. The results indicate that exponential gain coefficient of Ce:Cu:BSO is more than two times as that of non-doped BSO and the response time exhibits in microsecond level. Furthermore its exponential gain coefficient improves greatly compared with Ce:BSO’s at the same doping level of Ce, while its response time is less than Ce:BSO’s. The improvement mechanism of photorefractive effect of Ce:Cu:BSO crystal is investigated systematically.
