Abstract
In this paper a modified chalcogenide glass was studied by X-ray powder dif fraction, differential thermal analysis, infrared and Raman scattering spec troscopies. The study of this new matrix opens new perspectives to fabricat e Pr3+-doped fibers to operate as an optical amplifier in the 1.3 mum telec ommunications window. The Pr3+-doped 70Ga(2)S(3)-30La(2)S(3) glass was modi fied through the substitution of La2S3 by La2O3, which improves the thermal stability of these glasses without any modification of phonon energy. The possibility to pull a fiber from this glass system without any devitrificat ion is easily achieved.
