| 摘 要： | 通过数值模拟的方法,研究了有外加电场的中心对称光折变晶体中匹配高斯光束的动态演化及自偏转特性.结果表明,对于给定的与中心对称光折变晶体参量匹配的高斯光束,在晶体中能演化为稳定的孤子波；考虑扩散效应之后,匹配高斯光束的中心将发生自偏转.随着入射光强的增加,高斯光束中心的自偏转程度先增加后减小,转折处的入射光强度对应于最窄...

| Abstract: | Dynamical evolution and self-deflection of matching Gaussian beam in biased centrosymmetric photorefractive crystal were investigated numerically.The result indicates that,for a given centrosymmetric photorefractive crystal,a Gaussian beam which matches with its parameters can evolve into steady-state solitary wave.The diffusion effect can cause self-deflection of the matching Gaussian beam.The degree of self-deflection of matching Gaussian beam center increases first and reaches its maximum value with a ce... |
