摘　　要：本文用提拉法从熔体中生长了Ce:Fe:LiNbO_3晶体,并采用二波混合和简并四波混合方法研究和测试了晶体的全息衍射效率和相位共轭反射率.以Ce:Fe:LiNbO_3晶体作为存储元件和相位共轭镜,实现了光学实时全息关联存储.The Ce : Fe : LiNbO3 crystals were grown from meit by czochraski technique. Their holographic diffraction efficiency of phase conjugate reflectivity were measured and analysed by means of two-wave mixing and degenerate four-wave mixing. The optical associative memory in which Ce : Fe : LiNbO3 crystals were used as a storing element and a phase conjugate mirror was obtained.
