Optical vortices are light with orbital angular momentum, which has been found to have the effect of rotating molecules. Using optical vortices control of the metallic nanostructures and the chirality of azo polymers were reported photoisomerization. In this study, in order to develop the control of molecular orientation by optical vortices, we aim to clarify the interaction of optical vortices with cholesteric liquid crystals (CLCs).
