摘　　要：从理论上研究了有背景光辐照的光伏光折变晶体中非相干耦合光伏空间Manakov孤子对。结果表明:当两个耦合孤子的总强度远小于背景光时,孤子的耦合方程将转化为Manakov方程,推出了有背景光辐照的光伏光折变介质中的亮-亮、暗-暗和亮-暗Manakov孤子解,并对Manakov孤子对的特性进行了详细的讨论。The incoherently coupled Manakov photovoltaic solitons pairs in photovoltaic photorefractive crystals illuminated by incoherent uniform background are investigated theoretically.The result shows that the coupled soliton equations reduce to the Manakov equations when the total intensity of two coupled solitons is much lower than the illuminated by incoherent uniform background.The dark-dark,bright-bright and bright-dark photovoltaic soliton pair solutions of these Manakov equations are reduced.Moreover,the characteristics of these Manakov soliton pairs are also discussed in detail.
