Abstract
The effect of flow-reorientation coupling on to the relaxation process of refractive index grating in nematic liquid crystals has been theoretically investigated. It is shown that in case of oblique incidence of the two beams onto the homeotropic cell the shear flow induced by the electromagnetic field can enhance the amplitude of the director reorientation to about ten times.
