给出了具有轨道角动量的激光光束的非线性光学的详细公式。在介绍了这种扭曲光束的一般原理之后，发展了一个量子电动力学公式来表示它们与物质相互作用的光子学。给出了拉盖尔-高斯光束在大瑞利射程极限下的详细结果。通过对二次谐波产生的应用，说明了该理论在非线性光学中的应用。
A theory is presented for the detailed formulation of the nonlinear optics of laser beams endowed with orbital angular momentum. Following an introductory excursion into the general principles of such twisted beams, a quantum electrodynamical formulation is developed for representing the photonics of their interaction with matter. Detailed results are given for Laguerre–Gaussian beams in the large-Rayleigh-range limit. Utilization of the theory in nonlinear optics is illustrated by application to second-harmonic generation.
