摘要
推导出了光折变空间灰孤子在大光强和饱和光强条件下所满足的非线性波方程，并进行了数值求解，给出了大光强和饱和光强一维标量光折变灰孤子的复振幅空间分布．
Based on the Kukhtarav model,the nonlinear wave equations for highintensity and saturation regime gray spatial soliton in photorefractive media are derived and integrated numerically.The characteristics of the propagation constant of these self trapped optical beams are discussed.We also give a comparison of the intensity profieles between gray solitons and dark solitons.
