Abstract

The optical properties of praseodymium- doped glasses have attracted considerable attention recently for their potential application as a 1.3-μm optical amplifier. As a result, novel glass compositions are being developed and assessed. We have previously reported the properties of a series of novel Pr³⁺ glass compositions¹ for application in the second telecommunications window. The purpose of this work is to provide a complete evaluation of the radiative and nonradiative properties of Pr³⁺ in these materials, considering all radiative transitions, for other possible applications. Efforts are concentrated on novel heavy-halide glasses, namely, hafnium fluoride, indium fluoride, and cadmium fluorides and chlorides for which new transitions and improved quantum efficiencies are expected.
