We propose and demonstrate Sodium Zinc Molybdenum Tellurite glasses (Na 2 O-ZnO-MoO 3 -TeO 2 or NZMT) as suitable hosts for rare earth ion Holmium (Ho 3+ ) operating at 1.2m and 1.37m wavelength. The density, the refractive indices, the optical absorption have been measured. The Judd-Ofelt intensity parameters Ω 2, Ω 4, Ω 6, the radiative rates, the branching ratios, and the fluorescence lifetimes were calculated from Judd-Ofelt theory. Intense 1.2µm ( 5 I 6 → 5 I 8 ) and 1.37µm ( 5 S 2 , 5 Fdoi:10.2991/cmfe-15.2015.81 fatcat:nkw5tkkd5nhhhhpubljddkuasq
