We present a brief introduction to the orbital angular momentum of light, the subject of our theme issue and, in particular, to the developments in the 13 years following the founding paper by Allen et al. (Allen et al. 1992 Phys. Rev. A 45, 8185 (doi:10.1103/PhysRevA.45.8185)). The papers by our invited authors serve to bring the field up to date and suggest where developments may take us next.This article is part of the themed issue 'Optical orbital angular momentum'.
我们简要介绍一下光的轨道角动量,这是我们本期主题的主题,特别是自艾伦等人的开创性论文发表后的13年里该领域的发展情况。(艾伦等人,《物理评论A》,第45卷,第8185页(doi:10.1103/PhysRevA.45.8185),1992年)。我们特邀作者的论文旨在使该领域跟上时代步伐,并指出未来发展的方向。本文是“光学轨道角动量”主题特刊的一部分。
