中文摘要：

从理论上分析了具有不同Glass常数的背景光在晶体折射率空间分布相对变化中的作用,得到了折射率改变为负的晶体中形成亮、暗光伏孤子的条件.以此为基础,用532nm的e光作信号光、488nm的o光作背景光并不断变化背景光和信号光的功率,首次在实验上观察到了LiNbO3∶Fe晶体中亮光伏孤子的形成.

英文摘要：

The effect of background beam with different Glass constant on the relative spatial refractive perturbation in photovoltaic crystal was discussed, in which was introduced the concrete conditions for the formation of bright or dark photovoltaic spatial solitons in crystals with negative refractivity change. Based on the results, for what is to our knowledge the first time, the bright photovoltaic solitons was experimentally observed in LiNbO3：Fe by use of e-ray signal of 532nm and o-ray background illumination of 488nm.
