| 摘 要： | 基于光束在各向异性单轴介质中的傍轴矢量传输理论,导出了圆平顶高斯光束在单轴各向异性晶体中的传输公式,并利用此解析式作数值计算和分析了圆平顶高斯光束在单轴晶体中的传输,研究了各向异性介质对x方向偏振的圆平顶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圆对称性有较大影响.

| Abstract: | Based on the paraxial vectorial theory of the propagation of beam in uniaxially anisotropic media,the analytical propagation function of circular flattened Gaussian beams in uniaxially anisotropic crystal is derived.And some numerical simulations are preformed to study the effect of the anisotropy on the polarization properties of the diffracted circular flattened Gaussian beams in the output plane.The results show that the linear polarization state and symmetry of beam cannot remain the same during propagation due to the anisotropy of crystals. |
