Source abstract
Abstract
Abstract In this research, the optical properties of Er3+/Yb3+ co-doped phosphate glass have been studied to explore the potential of this glass system in laser and electronic amplifiers. The Judd–Ofelt (J-O) intensity parameter (Ωt) in the J-O model was established to determine the absorption intensity of the glass. The optical properties of the glass can be evaluated by various radiation parameters such as the radiative transition probabilities (Arad), stimulated emission cross sections (σe), branching ratios (βJJ'), maximum half-width values (Δλp), and the radiation lifetime (τrad) of the glass. It was found that in the case of Yb3+ as a sensitizer, the spectral properties of the Er3+ doped glass can be maximized. The data of Arad, βJJ', τrad, σe and Δλp obtained by Er3+/Yb3+ co-doping can find that the Er3+-doped sample undergoes 4I13/2–4I15/2 transition at 1.56 µm, and the stimulated emission cross section is greatly improved. The application prospects of the glass in solid near-infrared laser and electronic communication was discussed. According to the comprehensive discussion and analysis, the glass has great application potential.
