Holographic diffraction gratings recording in organically modified silica gels.
Abstract
The silica gel-methyl methacrylate organically modified ceramic is proposed for recording of volume holograms. Both low-spatial-frequency (54 line pairs/mm(-1)) and high-spatial-frequency (1400 line pairs/mm(-1)) holographic gratings were successfully recorded in the medium by interference of two coherent beams of 351.1-nm wavelength. High diffraction efficiencies (93%) and extremely low absorption and scattering coefficients were measured …
