Tunable Raman Gain in Transparent Nanostructured Glass-Ceramic Based on Ba₂NaNb₅O₁₅ †.

ABSTRACT: Stimulated Raman scattering in transparent glass-ceramics (TGCs) based on bulk nucleating phase Ba₂NaNb₅O₁₅ were investigated with the aim to explore the influence of micro- and nanoscale structural transformations on Raman gain. Nanostructured TGCs were synthesized, starting with 8BaO·15Na₂O·27Nb₂O₅·50SiO₂ (BaNaNS) glass, by proper nucleation and crystallization heat treatments. TGCs are composed of nanocrystals that are 10-15 nm in size, uniformly distributed in the residual glass matrix, with a crystallinity degree ranging from 30 up to 50% for samples subjected to different heat treatments. A significant Raman gain improvement for both BaNaNS glass and TGCs with respect to SiO₂ glass is demonstrated
