Abstract

A series of Er/Yb:LiNbO₃ crystals tridoped with x mol% In ³⁺ ions (x = 1, 2 and 3 mol%) was grown by Czochralski technique. Under 980 nm excitation, the strongest intensity of 1.54 μm emission was observed for 2 mol% In³⁺-tridoped Er/Yb:LiNbO₃ crystal. The UV-vis-infrared absorption spectra of In/Er/Yb:LiNbO₃ crystals were measured, and Judd-Ofelt (J-O) theory was carried out to predict the J-O intensity parameters (Ω_t), radiative lifetime τ_rad and fluorescence branching ratio β. The emission cross-section of the ⁴I_13/2 → ⁴I _15/2 transition of Er³⁺ ion was calculated by Füchtbauer-Ladenburg (F-L) method. The gain cross-section, estimated as a function of the population inversion ratio, allowed us to evaluate a potential laser performance of In/Er/Yb:LiNbO₃ crystal at 1.54 μm emission. The fluorescence lifetimes of the ⁴I_13/2 → ⁴I_15/2 transition in In/Er/Yb:LiNbO₃ crystals were measured.
