Abstract

Optical nonlinearity of liquid crystals (LC) in the isotropic phase can be enhanced by one order of magnitude by dissolving 0.1 percent of anthraquinone dye in the LC. The enhancement decrease when the LC transforms into the nematic phase. The same guest-host effect also exists in non-LC liquids. It can be explained by a model based on selective excitation of dye molecules and the change of guest-host interaction induced by optical excitations of the dye.
