Abstract

In this paper, a nanocomposite material obtained by a high niobium content glass belonging to the K₂O-Nb₂O₅-SiO₂ (KNS) glass-forming system is prepared and characterized. We focus on the investigation of spontaneous and stimulated Raman scattering. Strong changes of Raman spectra in nanocomposite material with respect to bulk sample are proved and discussed, while a significant enhancement of Raman gain (up to 25 times higher) and of its bandwidth with respect to SiO₂ glass is reported. This family of glasses is a promising candidate for next generation Raman gain applications for use in the format of integrated optics as well.
