Y$$_{3}$$Fe$$_{5}$$O$$_{12}$$ (YIG) films with a periodic-antidot-array structure fabricated by laser microprocessing is shown to exhibit clear characteristics of two-dimensional (2D) magnonic crystals. The experimental results demonstrate that the spin-wave-resonance spectra in the YIG films are modulated by the periodic antidot structure. The frequency and lattice constant dependences of the spectra are well reproduced by a numerical calculation based on magnonic band structures of the 2D magnonic crystals. Since the laser micro-processing is compatible with various thin-film fabrication methods, it can be a powerful tool for constructing magnonic crystals.
