【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.更多还原

【Abstract】 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.更多还原
