Abstract The paper presents the data on temperature measurements of the luminescence kinetics spectra of lithium niobate crystals with gradients of Yb and Er concentrations. It was found that heating the samples in the temperature range of 300–473 K leads to an increase in the luminescence spectrum in the range of 1480–1680 nm for the Er3+,Yb3+:LiNbO3 crystal and to a decrease for the Er3+:LiNbO3 crystal. Measuring the dependence of the gain in the weak signal mode at a wavelength of 1546 nm made it possible to establish that the signal does not decay and does not enter the saturation mode up to the pump power of 500 mW.

铌酸锂梯度晶体中ER3+、YB3+动力学谱的温度依赖性

摘要 本文介绍了铌酸锂晶体在 Yb 和 Er 浓度梯度下的发光动力学光谱的温度测量数据。发现在 300-473 K 的温度范围内加热样品导致 Er3+,Yb3+:LiNbO3 晶体的发光光谱在 1480-1680 nm 范围内增加，而 Er3+:LiNbO3 晶体的发光光谱减少. 测量波长为 1546 nm 的弱信号模式中增益的相关性，可以确定信号在高达 500 mW 的泵浦功率时不会衰减并且不会进入饱和模式。
