Record of dynamic and static holograms in thin fullerene-doped organic films

Under the Raman-Nath diffraction conditions the thin holographic gratings have been recorded in a promising class of (pi) -conjugate organic materials based on polyimide and 2- cyclooctylamino-5-nitropyridine. The drastic change of refractive index has been observed in the systems doped with fullerene C70. The results have been explained both by laser-induced conformational transformations of organic materials and by their spectral and thermal properties.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.
