- Researchers propose and demonstrate Sodium Zinc Molybdenum Tellurite glasses (Na2O-ZnO-MoO3-TeO2 or NZMT) as suitable hosts for rare earth ion thulium (Tm3+) operating at 1.47 mm wavelength. The density, the refractive indices, the optical absorption have been measured. The Judd-Ofelt intensity parameters 2, 4, 6, the radiative rates, the branching ratios, and the fluorescence lifetimes were calculated according to Judd–Ofelt theory. Intense 1.47 mm fluorescence was observed in these glass systems under 973-nm excitation. The bandwidth of the 3H4 ® 3F4 transition in NZMT glass is ~100 nm, which is significantly larger than that of fluoride glasses but less than that in KBG glasses. Measured fluorescence lifetimes of the 3F4® 3H6 and 3H4® 3F4 decay at room temperature were 2.842 and 0.323 ms respectively, and their quantum efficiencies were approximately 100% and 88.9%. From the data, it appears that Tm3+ doped NZMT glasses are promising materials for waveguide lasers and amplifiers operation at 1.40-1.52 mm wavelength range.
