Propagation of elliptical Gaussian beam in uniaxial crystal orthogonal to the optical axis

摘要: 基于光束在各向异性介质中的傍轴矢量传输理论，导出了椭圆高斯光束在各向异性单轴晶体中垂直于光轴的传输公式，并利用此解析式进行数值计算和分析，研究了各向异性介质对x方向偏振的椭圆高斯光束偏振特性的影响．研究表明，晶体的各向异性对光束的偏振和对称性有较大影响．

Abstract: Based on the paraxial vectorial theory of the propagation of beam in uniaxially anisotropic medium, the analytical formula for an elliptical Gaussian beam propagating in uniaxial crystal orthogonal to the optical axis is derived. And some numerical simulations were preformed to study the effect of the anisotropy on the polarization property of the diffracted elliptical Gaussian beam in the output plane. The results show that the linear polarization state and the symmetry of beam cannot remain unchanged during propagation due to the anisotropy of crystals.
