A method for laser induced hexagonal symmetry microstructures in an azobenzene containing polymer film is presented based on forward degenerate four-wave mixing. Multiple forward phase conjugate waves are observed. Three p-polarized input laser beams induce only one-dimensional gratings, but using a proper combination of s-polarized and p-polarized laser beams, hexagonal symmetry microstructures can be induced in the azobenzene polymer film. The experimental results indicate that both the periodic variations of light field intensity and the alternation of the resultant electric field polarization in the film are essential to the formation of the microstructures in the crystal.
