Abstract
With the goal of developing new mid-IR laser sources, Rare-earth doped low-phonon crystals and sulfide-based chalcogenide glasses are being explored. Low maximum phonon energy materials are necessary to minimize competing non-radiative decay processes such as multi-phonon relaxation (MPR). This work presents the results of a comprehensive mid-IR spectroscopic study on Dy3+ doped sulfide-based chalcogenide glasses, as well as comparative results from similarly doped chloride and fluoride crystals. Spectroscopic results will focus on absorption, fluorescence, and decay characteristics. From these measurements, laser relevant parameters such as cross sections and radiative lifetimes are calculated.
