摘　　要：本文对BaTiO3：Ce自泵浦相位共轭镜受寄生光的影响其相位共轭主光栅耦合强度的变化进行了数值求解，对非相干光擦除作用下的自泵浦相位共轭过程进行了理论分析，并且从相应的实验证实，用非相干光选择区域擦除能减少和抑制寄生光栅，从而能提高自泵浦相位共轭反射率。For BaTiO3.Ce self-pumped phase conjugator influenced by a parasitic light, we have given numerical results of coupling strength about phase conjugation grating. The self-pumped phase conjugation process under incoherent erasure has theoretically been analysed. It is also experimentally demonstrated that selective erasure for using incoherent light can lessen and suppress parasitic gratings. As a result, self- pumped phase conjugation reflectivity can be improved.
