摘要In this work, we report the 2.05 mu m emission and similar to 3 mu m broadband spectra of Ho2O3-doped 33GeO(2)-30TeO(2)-27PbO-10CaO (in mol%) glass under 640 nm laser excitation. Clear emission spectra due to the I-5(7)-I-5(8) transition and the I-5(6)-I-5(7) transition in Ho3+ are observed. The 2.05 gm emission intensity and the full width at half maximum (FWHM) of the similar to 3 mu m broadband depend on the Ho concentration. The peak stimulated emission cross-section of Ho3+ is 6.57 x 10(-21) cm(2) at 2.05 mu m, as calculated by the McCumber theory. The emission spectra are recorded and the maximum emission intensity at 2.05 mu m is obtained at a doping level of 0.5 mol% Ho2O3 in the glass. A broad and flat emission band from 2700 nm to 3050 nm is observed in 2 mol% Ho2O3-doped tellurium germanate glass. The lifetime of the I-5(7) state decreases with the increase in Ho3+ concentration due to non -radiative relaxation processes. An energy transfer coefficient of 271.88 mol(-1) s(-1) is obtained.
