摘要：
Spectral bandwidth of spontaneous Raman scattering of tellurite glasses was significantly widened upon introduction Of MoO3 or WO3. Tellurite glasses modified with MoO3 presented Raman scattering spectra with full width at half maximum of similar to 300 cm(-1) centered at Stokes shift of similar to 800 cm(-1) without much reduction of its relative Raman scattering coefficient. Such enhancements of the Raman scattering characteristics of the modified tellurite glasses, together with their good thermal stability, proposed their high potential as a wideband fiber Raman amplifier for optical communications. Broadening of the Raman scattering bandwidth is discussed in terms of structural changes accompanied. (c) 2005 Elsevier B.V. All rights reserved.
