摘要：

Spectroscopic properties of Er3+-doped Na2O-Sb2O3-B2O3-SiO2 glasses have been investigated for developing 1.5-mu m broadband fiber amplifiers. An intense 1.5-mu m near infrared emission with a broad full width at half maximum(FWHM) of 88 nm has been obtained for Er3+-doped 5Na(2)O-20Sb(2)O(3)-35B(2)O(3)-40SiO(2) glass upon excitation with a 980 nm laser diode. The obtained emission cross-section of the I-4(13/2) -> I-4(15/2) transition and the lifetime of the I-4(13/2) level of Er3+ ions are 6.8 x 10(-21) cm(2) and 0.36 ms, respectively. It is noted that the product of the emission cross-section and the FWHM of the glass, sigma(e) x FWHM, is as great as 598.4 x 10(-21) cm(2) nm, which is comparable or higher than that of Er3+-doped bismuth-based and tellurite-based glasses. These special optical properties encourage in identifying them as important materials for potential applications in high performance optics and optical communication networks. (c) 2007 Elsevier B.V.
