The formation, transverse effect and quasicrystal structure of azobenzene polymer films are reported.Using degenerate four-wave mixing experiments, the morphology of many islets in organic thin films was observed by scanning electron microscopy and polarized light microscope And the formation of a quasicrystal structure.The experiment proves that the structure of the pattern in the organic thin film can be controlled by the appropriate combination of polarization state of the written light and opens up a new road for the nanostructured technology of the organic thin film.
