We fabricate two-dimensional photonic quasicrystal lattices in iron-doped lithium niobate photorefractive crystal by a single amplitude mask. The experimental setup of this method is very simple and flexible without complicated optical adjustment system. It can be applied in almost any optical laboratories. We analyze the photonic quasicrystal lattices by plane wave guiding, Brillouin-zone spectroscopy and far field diffraction pattern imaging. The induced photonic quasicrystal lattices can exist stably for a long time in the photorefractive crystal. This method can be easily extended to generate more complex quasi-periodicity microstructures by designing the amplitude mask properly.
