Abstract

In this paper, the possibility to obtain new materials with both large Raman gain coefficients and spectral bandwidth is investigated. In particular, silica-niobia based glasses have been characterized by Raman spectroscopy. Our silica-based glass system (K2O-Nb2O5-SiO2 (KNS)) are obtained by a thermal treatment resulting in a nanocomposite material of easy and cheap production. Our glass composition have demonstrated both a strong Raman gain and a large bandwidth. These results can be related to nanostructured material domains.
