    This study proposes a new nonlinear laser-limiting method based on a one-dimensional photonic crystal with double defects. Further, the variation in the center wavelength of the transmission spectrum of a photonic crystal with the refractive index of the double defect layer is studied. The laser-limiting structures of nonlinear photonic crystals operating at 532 nm and 1064 nm are designed using the proposed method, and the high transmission of weak light and high blocking of strong light are achieved. The designed laser-limiting structure, (AB)6CAC(AB)6, is an one-dimensional photonic crystal with double defects. The laser-limiting structure used for 532 nm laser employs three types of media (A, B, and C), namely diamond, SrF2, and CS3-68 glass, respectively. The optical transmittance of this laser-limiting structure for weak light is 86.4%, and that for strong light is 0.02%. In contrast, the laser-limiting structure used for 1064 nm laser employs three types of media (A, B, and C), namely diamond, CeF3, and CdTe, respectively. The optical transmittance for weak light is 79.8% and that for strong light is 0.3%.
