Bessel beams: Diffraction in a new light期刊名称： Contemporary Physics作者： McGloin, D, Dholakia, K年份： 2005年期号： 第1期关键词： copper;EPR spectroscopy;nickel;N ligands摘要：Diffraction is a cornerstone of optical physics and has implications for thedesign of all optical systems. The paper discusses the so-called ''non-diffracting''light field, commonly known as the Bessel beam. Approximations to such beams canbe experimentally realized using a range of different means. The theoreticalfoundation of these beams is described and then various experiments that makeuse of Bessel beams are discussed: these cover a wide range of fields including non-linear optics, where the intense central core of the Bessel beam has attractedinterest; short pulse non-diffracting fields; atom optics, where the narrow non-diffracting features of the Bessel beam are able to act as atomic guides and atomicconfinement devices and optical manipulation, where the reconstruction propertiesof the beam enable new effects 内容由中国教育图书进出口有限公司引进
