Application of Judd-Ofelt Theory Upon Chlofluorophosphate Glass Doped with Erbium

A series of erbium doped glasses chlorofluorophosphates were prepared and characterized. The absorption spectra were analyzed to determine the Judd-Ofelt parameters. The optical performance of these doped  glasses suggesting the relevance of these glasses for optical fiber/ wave guide lasers and optical amplifiers. Keywords : amglass doped, rare earth, erbium, Judd-Ofelt parameters, laser, and optical plifier.
