Research Abstract	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.
