Abstract
Orientation of dyes and liquid crystals molecules in the field of laser radiation is considered taking into account anisotropy of molecular optical polarizability. A dependence of dyes and liquid crystals clusters energy on the strength of laser radiation electrical field, aperture of the light beam, optical polarizability anisotropy, order parameter and the number of molecules in a cluster, is derived. The angular distribution function of clusters is derived depending on the aperture of the light beam.
