In this work, we prepared and studied spectroscopic properties of Dy3+ ions in lithiumsodium aluminoborate glasses. Judd - Ofelt theory has been used to evaluate intensity parameters Ωλ (λ = 2, 4, 6) by analyzing the absorption spectrum of ABLN: Dy3+ glass, and calculated the radiative transition probabilities, branching ratios, radiative lifetimes of 4F9/2 excited level, stimulated emission cross - section for selected.
