摘　　要：为了得到中心对称单光子光折变晶体中空间灰孤子族的结果,基于中心对称光折变晶体中空间灰孤子的基本理论,推出了中心对称光折变晶体中灰空间孤子数值积分解,对孤子的特性进行了数值模拟。结果表明:这些空间灰孤子族是由偏振方向和波长都相同且互不相干多数光束耦合形成的。当灰孤子族中仅含有一个或两个分量成分,它就变成单光子灰孤子或非相干耦合灰-灰孤子对。To study the grey spatial soliton families in one-photon centrosymmetric photorefractive crystals,we derive theoretically the expressions of normalized spatial profiles of the centrosymmetric grey spatial soliton families from the soliton theory in biased centrosymmetric photorefractive crystals and investigate the characteristics of the solitons.The numerical results show that these gray solitons families can be obtained from the multi couoled beams,which share the same polarization,wavelength,and are incoherent with one another.When only one or two components are involved,these grey spatial soliton families degenerate into grey spatial soliton or soliton pairs automatically.
