摘要
偏振在光与物质相互作用中扮演着重要的角色。过去几十年里,绝大多数研究工作都基于偏振单一且均匀分布的标量光场。近年来,随着光场产生与操控技术的不断发展,空间偏振非均匀分布的矢量光场逐渐引起人们的关注。矢量光场具有多维可调控的自由度以及独特的焦场属性,在经典与量子通讯、光学操控和显微成像等领域具有重要的研究价值与广泛的应用前景。矢量光场与物质相互作用的研究不仅丰富了人们对光场矢量特性的认识,也推动了基于不同介质实现光场调控的新发展。原子介质对光场偏振具有较高的敏感性,容易形成原子极化,并且具有更多的调控自由度,是探索矢量光场特性与实现矢量光场调控的理想平台。本文回顾了近年来矢量光场与原子介质相互作用的研究进展,重点介绍了原子介质与矢量光场在空间极化调控、相干调控、频率转换和非线性传输等研究领域的相关工作,并对该领域的未来发展趋势进行了展望。
The polarization of the light field plays an important role in the interaction of light and matters.In the past few decades,most research works have been based on scalar light fields with a uniform distribution of polarization.Recently,with the development of light field generation and manipulation,the vector beam with non-uniform spatial polarization distribution has attracted much attention.The vector beam has multidimensional controllable degrees of freedom and unique focal field properties,which offers great research value and broad application prospects in classical and quantum communication,optical manipulation,microscopic imaging etc.The study of the interaction between the vector beam and matters enriches the understanding of the vector properties of the light field,but also promotes the new development of light field manipulation in different media.Due to easy polarization and more controllable degrees of freedom,the atomic medium provides an ideal platform for exploring the characteristics of the vector beam and realizing the manipulation of the vector light field.In this review,we highlight the recent progress in the interaction between vector beams and atomic media,such as spatial anisotropy,coherent control,frequency conversion,and nonlinear transmission using vector beams.Specifically,we first describe how to manipulate a vector beam using the spatial anisotropy of atomic ensembles.Vector beam has a spatially structured polarization distribution that can produce unique atomic polarization.On the one hand,atomic polarization depends on the polarization state of the light field.As a result,the intensity and polarization of the light field can be modulated by spatially atomic polarization.On the other hand,magneto-optical rotation modifies the polarized state of the light by causing the anisotropy of the atomic medium with a magnetic field.This technique could be used to control the polarization and intensity distribution of the vector beam.Secondly,many research teams typically employ a single path or
