摘　　要：为了得到双光子光折变非相干耦合屏蔽空间孤子族的结果,对外加电场双光子光折变晶体中非相干屏蔽孤子族进行了数值研究.结果表明:这种孤子族是由偏振态和波长都相同的多束互不相干光耦合而成的.当双光子非相干耦合屏蔽孤子族中只含有两个光束分量时,就退化为双光子屏蔽孤子对.In order to obtain the results of the two-photon incoherently coupled screening soliton families,the incoherently coupled screening soliton families in basid two-photon photorefractive crystals were numerically studied.The result showed that these soliton families were established by the multiple incident solitary beams with the same polarization,wavelength,and mutual incoherence.Two-photon incoherently coupled screening soliton families reduced to screening soliton pairs when they contained only two components.
