The effect of introducing TeO2 on 2.7 #x00B5;m emission in ZBLAN glass

摘要

A novel erbium ions doped fluoro-tellurite glasses were prepared, and intense 2.7 µm emission was observed. The present Er3+-doped fluoro-tellurite glasses with large 2.7 µm emission cross-sections (6.32×10−21 cm2) indicates that it has a very promising application for solid state lasers around 3 µm.
