Description/Abstract

Fluorescence spectra of Pr3+-doped gallium lanthanum sulphide (GLS) chalcogenide glass at 300 and 1.9K are presented. Energy-selective spectroscopy is performed for the 1D2 and 3P0 levels at both temperatures, and the results show that there is strong correlation between the inhomogeneous profiles of ground and excited states, a situation which does not normally occur in rare-earth doped glasses. This is explained in terms of the relative contributions to the broadening from the nephelauxetic effect and crystal field broadening in this system. Its implication for the 1.3µm amplifier based on Pr3+ in this host is assessed.
