Abstract

It is shown that a squared Laguerre-Gaussian (LG) vortex beam is Fourier-invariant and retains its structure at the focus of a spherical lens. In the Fresnel diffraction zone, such a beam is transformed into superposition of conventional LG beams, the number of which is equal to the number of rings in the squared LG beam. If there is only one ring, then the beam is structurally stable. A more general beam, which is a “product” of two LG beams, is also considered. Such a beam will be Fourier-invariant if the number of rings in two LG beams in the “product” is the same. The considered beams complement the well-known family of LG beams, which are intensively studied as they remain stable during their propagation in turbulent media.

傅里叶不变的平方拉盖尔高斯涡旋光束

证明了方形拉盖尔-高斯(LG)涡旋光束是傅里叶不变的，并在球透镜的焦点处保持其结构。在菲涅耳衍射区，这样的光束被转换成传统LG光束的叠加，其数量等于LG光束的平方中的环数。如果只有一个环，那么梁是结构稳定的。还考虑了更一般的光束，即两个LG光束的“乘积”。如果“乘积”中两个LG光束中的环数相同，那么这样的光束将是傅里叶不变的。所考虑的光束补充了众所周知的LG光束家族，LG光束被深入研究，因为它们在湍流介质中传播期间保持稳定。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
