【 摘 要 】

Rare earth iondoped solid state materials are the most important active media of near-infraredand visible lasers and other photonic devices. In these ions, the occurrenceof Excited State Absorptions (ESA), from long lived electronic levels, is commonplace.Since ESA can deeply affect the efficiencies of the rare earth emissions, evaluationof these transitions cross sections is of greatest importance in predictingthe potential applications of a given material. In this paper a detailed descriptionof the pump-probe technique for ESA measurements is presented, with a reviewof several examples of applications in Nd3+, Tm3+ andEr3+ doped materials.
