Abstract

Abstract: In this research, the optical properties of Er 3+ /Yb 3+ 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 ( Ω t ) 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 ( A rad ), stimulated emission cross sections ( σ e ), branching ratios ( β JJ' ), maximum half-width values (Δ λ p ), and the radiation lifetime ( τ rad ) of the glass. It was found that in the case of Yb 3+ as a sensitizer, the spectral properties of the Er 3+ doped glass can be maximized. The data of A rad, β JJ', τ rad, σ e and Δ λ p obtained by Er 3+ /Yb 3+ co-doping can find that the Er 3+ -doped sample undergoes 4 I13/2 – 4 I15/2 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.
