dc.descriptionA study of the broadband near-infrared emission in Pr3+ single doped and Pr3+/Yb3+ codoped tellurite-tungstate glasses for optical amplification is presented. In the Pr3+ single doped samples pumped at 474 nm the emission band at 1480 nm presents a FWHM of similar to 140 nm. The Yb3+ addition produces a FWHM broadening up to 155 nm, achieved through the (1)G(4)-H-3(5) transition. The emission spectra when the codoped sample is pumped at 980 nm shows efficient energy transfer from Yb3+ to Pr3+ resulting in an intense Pr3+ emission around 1330 nm. This shows that changing the pump wavelength it is possible to select the D-1(2)-(1)G(4) or the (1)G(4)-H-3(5) transition, displacing the emission band from similar to 1480 to similar to 1330 nm.
