| 摘 要： | 为了证明在有外加电场的双光子光伏光折变介质中存在着稳态屏蔽光伏空间灰孤子,采用理论分析的方法导出了双光子屏蔽光伏空间灰孤子空间包络的积分表达式.数值分析了孤子灰度取不同数值的时孤子归一化包络的变化行为.结果表明:屏蔽光伏灰孤子的最小光强和半峰全宽随孤子灰度数值的增加而增加,随其减小而减小.双光子光折变屏蔽光伏灰孤子可以...

| Abstract: | To prove the existance of grey screening-photovoltaic spatial solitons in biased two-photon photovoltaic photorefractive crystals under steady-state conditions,the expression of profile for two-photon grey screening-photovoltaic spatial solitons was deduced based on theoretical analysis.The dynamical behavior of spatial profile was analyzed numerically under different greyness.The results show that the minimum intensity and FWHM of the grey screening-photovoltaic solitons will increase(decrease) as the valu... |
