| Abstract: | In this paper, BGO and Bi:BGO crystals have been grown using CZ method. The reflectivities and response times of phase conjugation have been measured. The reflectivity of Bi:BGO is found to be two tirries of that of BGO crystal. The relation between reflectivity and applied electric field, and the mechanism of photorefraction of BirBGO are studied. |
