Abstract
Er

-doped and Er
3+
/Yb
3+
-codoped materials have played an important role in the development of broadband erbium-doped fiber amplifiers (EDFA) at the third communication window for their potential laser applications. Therefore
the choice of host material is very important in the development of more efficient op-tical amplifiers based on Er
3+
-doped glasses.The new Er

glass was prepared by the technique of high-temperature melting. The thermal stability
absorption spectra
fluorescence spectra and FT-IR spectra were measured and investigated. The effect of OH
-
on the spectro-scopic properties of glass sample was discussed. The Judd-Ofelt theory analysis on the absorption spectra was performed and compared with other glass hosts. The oscillator strength
spontaneous emission probability
radiative lifetime and emission branching ratio of several Er
3+
transitions were calculated according to the obtained Judd-Ofelt parameters. It was found that this studied glass has good thermal stability and it is a perfect candidate material for fiber drawing. The Judd-Ofelt parameters deriving from the absorption spectra were acquired as follows: Ω

. The broad FWHM(77 nm) was obtained from the fluorescence spectra and the large stimulated emission cross-section σ
e
peak
(8.7×10
-21
cm
2
) was calculated by the McCumber theory. The product of FWHM× σ
e
peak
is larger than those of other glass hosts
which indicating that this studied glass may be a potentially useful candidate material host for broadband optical amplifier. In addition
the fluorescent intensity and lifetime of the
4
I
13/2
level of Er
3+
ions will decrease with the existence of OH
-
content. The lifetime of the
4
I
13/2
level of Er
3+
ions increase from 1.7 ms to 2.31 ms after removing water during the melting process.
