摘　　要：为了得到有非相干背景光辐照的低振幅光伏空间孤子的结果,对非相干均匀背景光辐照下光伏光折变晶体中低振幅空间孤子进行了研究。给出了低振幅光伏明和暗孤子的解析表达式,并推导出了孤子宽度的显式表达式。In order to obtain result of the low-amplitude photovoltaic spatial solitons illuminated by incoherent uniform background.The low-amplitude spatial solitons in photovoltaic photorefractive crystals illuminated by incoherent uniform background are investigated theoretically.The analytical solutions for both the bright and dark low-amplitude two-photon screening-photovoltaic spatial solitons in photorefractive crystals are obtained.The explicit expressions for the width of these spatial solitons are presented.
