Scattering property of fluorine-doped silica glasses

The Rayleigh scattering coefficients of fluorine (F) doped silica glasses are invertigated experimentally and theoretically. They are measured for F-doped silica glass preforms fabricated by the VAD method. It is clarified that the Rayleigh scattering coefficients of F-doped silica glasses increase with increasing F concentration because the concentration fluctuation increases.
