摘　　要：研究了入射位置对互抽运相位共轭特性的影响.通过强度相等的两束光对称入射到Cu:KNSBN晶体上,进行鸟翼式互抽运相位共轭实验研究,获得了互抽运相位共轭光输出随着入射位置的变化存在最大值.并从理论上分析了入射位置对鸟翼式互抽运相位共轭机制的作用,指出入射位置对晶体内互抽运光回路、耦合系数的影响,及在互抽运相位共轭效应中存在一个最佳入射位置.The influence of the incident position on bird-wing phase conjugation properties is investigated. Based on bird-wing phase conjugation experiment in Cu. KNSBN crystal, the maximum output of phase conjugation is founded with changes of incident position by two symmetric beams of equal intensity. The action of incident position on bird-wing phase conjugation is analyzed theorically. The relation of incident position with beam path and beam-coupling coefficient is built. The optimal incident position in bird-wings phase conjugation is given.
