摘要
对外加电场的中心对称双光子光折变介质中两束偏振方向和波长都相同的互不相干光束的耦合进行了研究,预言了非相干耦合暗-暗、亮-亮及亮-暗中心对称双光子屏蔽空间孤子对的存在.
The coupling of two mutually incoherent optical beams with the same polarization and wavelength in two-photon centrosymmetric photorefractive crystals is studied.The result shows that incoherently coupled dark-dark,bright-bright and bright-dark screening soliton pairs in centrosymmetric photorefractive crystals are possible due to two-photon photorefractive effect.
