对有外加电场的光伏光折变晶体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 ,证明非相干耦合亮 暗屏蔽光伏孤子对的存在 .
The coupling of two mutually non-coherent beams with the same polarization direction and wavelength in photovoltaic photorefractive crystal with applied electric field is studied, and the existence of incoherently coupled bright and dark shielding photovoltaic soliton pairs is proved.
