|
摘要
为了制备高质量涡旋光,对基于Sagnac干涉仪的涡旋光制备方法进行了理论分析、改进设计和实验验证.介绍了高斯光束叠加和附加相位差π产生的原理,在分析干涉回路对横向剪切量影响的基础上,搭建了基于Sagnac干涉仪的涡旋光制备装置,给出了搭建实验平台的相关注意事项,并利用本方法分别制备出拓扑荷数为+1、-1的涡旋光.涡旋光在不同传播距离下拓扑荷数始终保持为+1或-1.基于光斑可调的改进实验装置可有效提高涡旋光质量.
In order to generate high-quality optical vortices,this paper presents theoretical analysis,improved design and experimental demonstration of a novel approach for optical vortex generation based on Sagnac interferometer.The additional phase differenceπis introduced,based on analyzing the influence of the interference loop on the shear amount,a optical vortex generation setup on the basis of a Sagnac interferometer is built,then the related considerations are given and optical vortices of topological charge+1 and-1 are generated respectively.The intensity distribution and interference patterns at various propagation distance are experimentally recorded and analyzed with topological charge keeping+1 and-1.The improved setup can generate optical vortices with higher quality.
