erbium

Le dopage des ions erbium est beaucoup plus élevé que celui du verre de quartz, de sorte que le gain par unité de longueur est élevé.
The doping of erbium ions is much higher than that of quartz glass, so the gain per unit length is high.

EFTA States may, in some instances, finance an SGEI from charges or contributions paid by certain undertakings or users, the revenue from which is transferred to the undertakings entrusted with the operation of that SGEI.
Erbium et Ytterbium verres co-dopés, la plupart du temps de types de phosphate, largement utilisés dans plusieurs domaines différents comme la dermatologie laser, la télécommunication, et la spectroscopie de dégradation induite par laser (LIBS).
Erbium and Ytterbium co-doped glasses, mostly of phosphate types, widely used in several different fields like dermatology laser, telecommunication, and Laser-induced breakdown spectroscopy (LIBS).
Cependant, cette vaste plage spectrale empêche l'utilisation d'amplificateurs à fibre dopée à l’erbium, lesquels fonctionnent mieux autour de 1550 nm, et limite la portée maximale des déploiements CWDM à 60 ou 80 km.
However, this broad spectral range prevents using erbium-doped fiber amplifiers, that work best around 1550 nm, and accordingly limits the maximum range of CWDM deployments to about 60 or 80 km.
Typiquement, le DO fortement dopé : YAG, environ 50 % d'atomes d'yttrium remplacés par Erbium, est utilisé comme milieu laser pour une longueur d'onde de 2940 nm.
Typically, highly doped Er:YAG, about 50% Yttrium atoms replaced by Erbium, is used as laser medium for 2940 nm wavelength.
