Spatiotemporal modeling of mid-infrared photoluminescence from terbium(III) ion doped chalcogenide-selenide multimode fibers
Autor: Zhuoqi Tang, Emma R. Barney, L. Sojka, Trevor M. Benson, David Furniss, Slawomir Sujecki, Angela B. Seddon, Dinuka Jayasuriya
Publikováno v: Journal of Rare Earths
A numerical model was developed to study the time dynamics of photoluminescence emitted by Tb3+ doped multimode chalcogenide-selenide glass fibers pumped by laser light at approximately 2 μm. The model consists of a set of partial differential equat
