摘要
Direct intracavity thermal loading measurements have been performed on diode pumped Yb3+ doped LiNbO3:MgO laser crystals. The fractional thermal loading has been found to be strongly dependent on the Yb3+ concentration, decreasing more than 40% when the Yb3+ concentration increases from 0.5 to 2 at. %. From the analysis of the concentration dependence of the fractional thermal loading, the intrinsic fluorescence quantum efficiency (free of radiation trapping) of Yb3+ ions in LiNbO3:MgO crystals has been determined and the role of radiation trapping among Yb3+ ions is discussed.
