Cadmium mixed halide glasses exhibit lower peak phonon energy than conventional fluorozirconate glasses. New glass compositions doped with Pr3+-ions were fabricated using controlled atmosphere melting and casting techniques. The optical properties of new bulk glasses were studied by spectruscopic techniques. The significance of an empirically derived total loss curve for bulk glass is examined for the design of a 1.3 µm amplifier. The concentration effects of Pr3+-ions as a dopant in the glass were studied, and its absorption cross-section measured to establish the ground state absorption in bulk glass. The thermal stability of mixed halide glasses was studied by differential scanning calorimetry. and an appraisal of their devitrification behaviour is presented.
