Abstract
Two erbium doped germanate glass samples prepared by sol-gel process and melting and casting method, respectively, have been characterized. A fluorescence lifetime of 2.5 ms at the 4I13/2 level and a very broad bandwidth (FWHM: 53.7 nm) around 1.55 μm have been observed for the sol-gel sample. The fluorescence lifetime and the spectrum bandwidth for 1.535 μm transition for the sample fabricated by the melting and casting technique were measured to be 10 ms, and 19 nm (FWHM). The cooperative up-conversion coefficient is measured to be 1.3×1018 cm3/s for the sample with an erbium concentration of 2.69×1020 ions/cm3.
