OVERVIEW In theory, any molten material can form a glass when quenched fast enough.
Most natural glasses are based on silicates and for thousands of years only alkali/alkaline …

Abstract The core-clad Tb 3+-doped Ga-Ge-As-Se/Ge-As-S chalcogenide glass fiber is
fabricated and tested in laser experiment. To prepare the high-purity terbium doped Ga-Ge …

This paper provides an overview of mid-infrared lasers based on rare-earth-ion-doped
selenide glasses. Laser action was demonstrated at the transitions between the first excited …

This article deals with sulfur and selenium-based glasses doped with rare earth ions. It

Abstract 4.9–5.5 µm laser oscillations were observed in high-purity bulk terbium-doped Ge
36 Ga 5 Se 59 glass pumped by pulsed 2.93 µm Er: YAG laser. This is the first evidence of …

A method for preparing high purity rare earth elements (REEs) doped chalcogenide glasses,
in which all components of the charge (Ge, Sb, Ga, Se) and REEs are loaded and subjected …

The use of a 3D-printing additive manufacturing process is reported for the first time for the
extrusion of chalcogenide glasses by using a filament feed. Several challenges were …

Abstract Quaternary Ge-Sb-Se-Te chalcogenide thin films were fabricated by rf magnetron
sputtering from Ge 19 Sb 17 Se 64− x Te x (x= 5, 10, 15, 20) sputtering targets in order to …

We present spectroscopic properties of the low-maximum-phonon energy host material,
barium fluoride (BaF_2) doped with Er^ 3+ ions. Following optical excitation at 800 nm, Er …

Elemental and heterophase impurities in some rare-earth elements (Ce, Pr, Nd, Tb, and Dy)
and features of their influence on optical and emission properties of doped chalcogenide …
