Physical and Stimulated Emission Cross Section (SEC) Properties of Nd³⁺ Doped Lithium Fluorophosphate (LFP) Glasses

Abstract:

This work describes a study that utilizes the Nd³⁺ ions (1.0 mol%) doped in glass material with the chemical formula 59P₂O₅ - 20Li₂O - 10AlF₃ - 10NaF. To obtain a glass medium with good homogeneity, all samples in the form of powder were mixed thoroughly and melted at 1100 °C for 3 hours. This sample preparation method is widely known as the melt-quenching method. The cutt and polish process is carried out to obtain a proportional and highly transparent of glass sample. Several parameters of physical properties were measured and then calculated to obtain the values of other parameters. The optical properties and stimulated emission cross sections (ECS) of a glass medium were obtained by observing the absorption and emission spectra. Based on the analysis of ECS, it was found that the radiative lifetime (τR) for Nd3+ ions experimentally and calculated were 132μs and 248μs respectively. Meanwhile, the quantum efficiency is achieved up to 53%
