    Abstract

    New glasses which exhibit a broadband Raman spectral response have been prepared and characterised for their Raman cross section and gain performance. Results on three different glass compositions in the system [(100-x)NaPO3-xNa(2)B(4)O(7)]: TiO2/Nb2O5=1 are summarised. The impact on the Raman properties of changing the phosphorus to boron ratio while maintaining the TiO2/Nb2O5 molar ratio equal to one, was examined. Polarised spontaneous Raman measurements are presented, and a comparison between the experimentally obtained Raman gain coefficient and that predicted from spontaneous Raman cross section measurements is made. Results obtained show that these glasses exhibit similar or slightly higher Raman gain coefficients than that of SiO2, with a spectral bandwidth almost five times greater (similar to 1300 cm(-1)).
