Abstract

The effect of starting materials purity, crucible material, and melting conditions on the optical scattering of AlF3-based glasses has been investigated. Platinum and vitreous carbon crucibles have been used to melt the glasses under nitrogen and reactive atmosphere (RAP) conditions. The optical quality of the bulk glass was evaluated by molecular light scattering in the Mie and Rayleigh regimes as a function of scattering angle and polarization at 0.647 μm. From an analysis of the angular scattering of both vertically and horizontally polarized beams, the sizes of the scattering sites have been estimated to be in the range of 0.02 to 2.0 μm. Glasses made with EM (BDH Limited) materials and melted in platinum crucibles without any reactive atmosphere exhibit lower values of scattering losses than those melted in the vitreous carbon crucibles under RAP.
