Abstract

Infrared emission at 1.2, 1.25, 1.67, 2.0, 2.2, 2.9, 3.9, and 4.9µm is measured in holmium (Ho3+) doped gallium lanthanum sulphide (GLS) glass. Branching ratios, radiative quantum efficiencies, and emission cross sections are calculated from lifetime, absorption, and emission measurements using Judd-Ofelt analysis and the Füchtbauer-Ladenburg equation. The fluorescence band at 3.9µm coincides with an atmospheric transmission window and the fluorescence band at 4.9µm overlaps with the fundamental absorption of carbon monoxide, making the glass a potential fibre laser source for remote sensing and gas sensing applications. This is the first time this latter transition has been reported in any holmium doped host.
