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 (K 2 O-Nb 2 O 5 -SiO 2 (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.

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 (K 2 O-Nb 2 O 5 -SiO 2 (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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
