Diffraction of light beams is investigated in the first forbidden band gap of photonic crystal. The approach is based on the well-known Floquet-Bloch method. Transverse plane beam structure and central angular spectrum component were calculated numerically.Our computations show that the Gauss beam profile structure insignificantly changes but an attenuation character modifies noticeably under nonlinearity.
