Abstract: Ten symmetrical photonic quasicrystals can be created by interference of five laser beam by theoretical analysis. In the experiment in order to simplify the optical path, five making beams is obtained by parallel light diffracted by five gratings. Through adjusting the distribution of five gratings and grating constant, the required beam deflection angle is obtained. And the measured lattice constants are coincident well with the calculated values.

Key words: holography, diffraction gratings, photonic quasicrystal
