摘　　要：考察了x方向偏振cos Gaussian光束沿光轴方向入射进单轴各向异性晶体的衍射性质,基于解各向异性介质边值问题的一般方法得到了衍射光场分布的解析表达式,进而借助于数值方法讨论了各向异性介质对x方向偏振cos Gaussian光束的偏振特性的影响。结果表明,在适当参数条件下,有可能获得均匀分布的偏振场分布。Diffraction of polarized cos-Gaussian beams along the optical axis of uniaxially anisotropic crystals was investigated.Based on a general method for solving boundary value problems in anisotropic medium,an analytic expression of the diffracted light field was obtained.The effects of the anisotropy on the polarization properties of the diffracted light beams have been elucidated.
