| 摘 要： | 为了获得有外加电场的双光子光伏光折变介质中存在着稳态非相干耦合屏蔽光伏空间孤子族的结果,对外加电场的双光子光伏光折变介质中多束偏振方向和波长都相同的互不相干光束的耦合进行了理论研究。结果表明:双光子非相干耦合屏蔽光伏孤子族可以看成是屏蔽孤子族和光伏孤子族的统一形式。当光伏场可忽略时,屏蔽光伏孤子族就转化为屏蔽孤子族;而当外加电场不存在时,屏蔽光伏孤子族相当于开路和闭路条件下的光伏孤子族;当孤子族中只含有2个光束分量时,孤子族就变为屏蔽光伏孤子对。

| Abstract: | In order to obtain the incoherently coupled screening-photovoltaic soliton families in biased two-photon photovoltaic photorefractive crystals under steady-state conditions,the coupling of multiple mutually incoherent optical beams with the same polarization and wavelength in two-photon photovoltaic photorefractive crystals is theoretically studied.The results show that the screening-photovoltaic soliton families can be considered as the united form of screening soliton families and photovoltaic soliton fam... |
