| 摘 要： | 为了得到双光子非相干耦合光伏孤子族的结果,采用数值模拟方法,对稳态情况下多束互不相干的光束在双光子光伏光折变晶体中的传播进行了研究。结果表明:具有相同偏振和相同波长的多束互不相干的入射光束可在晶体中形成双光子非相干耦合光伏孤子族。当入射光束中仅包含两个分量时,孤子族就转化为光伏孤子对。并用双光子光伏光折变晶体Cu:KNSBN和LiNbO3进行了分析说明。研究结果可为空间光孤子理论的发展提供理论依据。

| Abstract: | In order to obtain results of the two-photon incoherently coupled photovoltaic spatial soliton families,the propagation of multiple mutually incoherent optical beams in two-photon photovoltaic-photorefractive crystal is numerically investigated under steady-state conditions.It is shown that two-photon incoherently coupled photovoltaic soliton families can be established in the crystals by the mutually incoherently incident beams with the same polarization and wavelength.Such soliton families reduce to photo... |
