    摘要: The invention concerns an optical structure with non-linear optical properties comprising at least one stack comprising a central filter (1) and two optical sandwiching elements (2,3) between which said central filter (1) is interposed, wherein said central filter (1) is in a sol-gel matrix material, said material being doped with at least one optical limiting doping agent, the central filter (1) and the two optical elements (2,3) on either side thereof being assembled by bonding layers (4a, 4b) of a material based on the same sol-gel matrix as that of the central filter, the optical elements (2,3) on either side of the central filter (1) and the bonding layers (4a, 4b) each having a refractive index equal to that of the material of the central filter or only differing from this refractive index within a range of plus or minus 0.05, preferably within a range of plus or minus 0.02.
