Abstract: Since the interference of two laser beams propagating in opposite directions in a medium can form a 1-D periodic structure volume hologram which can be taken as 1-D photonic crystal or 1-D laser holographic photonic crystal, the dependent relationship of the forbidden band on incident angle, recording wavelength, medium refractive index as well as modulation of refractive index in the transmission spectrum of 1-D laser hologram photonic crystal was investigated with eigen matrix. The results show that the forbidden band moves towards the short wavelength and its width decreases as the incident angle increases or the laser wavelength, the refractive index of medium and the modulation of refractive index decreases.
