摘要

摘要: 为了得到有偏压的中心对称双光子光折变晶体中存在多变量空间灰孤子的结果,基于中心对称双光子光折变晶体中空间灰孤子的基本理论，采用数值方法推导出了中心对称双光子多变量空间灰孤子归一化包络解的积分形式,并对其特性进行研究。结果表明：这种多变量空间灰孤子是由多束偏振方向和波长都相同的互不相干光束耦合形成的。当多变量空间灰孤子只包含有1个或2个光束分量成分时，它自动退化到中心对称双光子空间灰孤子或中心对称双光子非相干耦合灰灰空间孤子对的情况。当这一多变量空间灰孤子在有偏压的中心对称双光子光折变晶体中传播时，各分量成分光束都能稳定传播。

Abstract: To study multi-variable gray spatial soliton in biased centrosymmetric two-photon photorefractive crystals based on the theory of gray soliton in centrosymmetric two-photon photorefractive crystals, we derived the expressions of the normalized envelope solution of the centrosymmetric two-photon multi-variable grey spatial soliton numerically and investigated the characteristics of soliton. The results show that the multi-variable gray soliton is obtained by the coupling of the multi-beams which share the same polarization, wavelength and independent of each other. When only one or two variables are involved, the multi-variable gray spatial soliton degenerates into centrosymmetric two-photon multi-variable grey spatial soliton or incoherently coupled soliton pairs. When the multi-variable gray spatial soliton propagates in biased centrosymmetric two-photon photorefractive crystals, all the components propagate stably.
