Abstract
The optical absorption of tetrahedrical anions such as phosphates and sulfates has been studied in fluorozirconate glasses. A ternary fluoride glass in the system ZrF4-BaF2-LaF3, was doped with calculated amounts of KHSO4 or NaPO3. A significant reduction of the OH-absorption has been achieved using a low temperature fluorination treatment and a high temperature refining under a very dry atmosphere. A minimum transmission loss of 58 dB/km at 2.9 μm was observed on a fiber 60 meters in length. Increasing heating time or temperature for the refining stage however results in higher scattering losses.
