Interactions between materials and the light with the helicoidalwavefront structure through the orbital angular momentum of photons

本研究的目的是讨论在线性和/或非线性光学效应的手征材料之间的手征相互作用的可能性和螺旋传播的光携带轨道角动量，所谓的，Laguerre-Gaussan光束。本文主要用几种不同的光学方法研究了B4螺旋纳米丝相的巨畴结构。然而，在这些光学过程中没有观察到显著的效果。这一结果与其他研究小组报告的实验和讨论一致。

This study is aimed at discussing the possibility of chiral interactions in linear- and/or nonlinear optical effect between chiral materials and a helically propagating light carrying orbital angular momentum, so called, Laguerre-Gaussan beam. Giant domains of the B4 helicalnanofilament phase of bent-core molecules are mainly investigated by several different optical schemes. However, no significant effect could be observed in these optical processes. This result is consistent with experiments and discussions reported by other research groups.
