Mie scatter in the KF-CaF2-AlF3-BeF2 glass system.
01 January 1985
Halide glasses are of interest for long wavelength (>1micrometer) optical fiber applications because of potential low Rayleigh scatter and multiphonon losses. However, due to the ionic character of the materials involved, precipitation of one or more phases may readily occur in compound glasses. It is shown, herein, that there are certain quasi-stable regions in the KF-CaF2-AlF3-BeF2 system that may permit extrusion from the molten state or pulling from preforms without nucleation of precipitates.
