摘要：

Two-photon ultraviolet laser excitation of Nd:YLiF4 was studied via the observation of the vacuum ultraviolet fluorescence from localized states of the 4F(2)5d configuration of the Nd3+ ion. Details of the laser excitation schemes, the fluorescence spectra, and the excitation laser intensity dependence of the fluorescence signals an discussed. A series of experiments demonstrated that the vacuum ultraviolet 4f(2)5d --> 4f(3) fluorescence spectrum following two-photon excitation is independent of the excitation laser wavelength. Our studies also revealed significant fluorescence reabsorption effects. Comparisons are made with earlier single-photon excitation studies in this system. (C) 2000 Elsevier Science B.V.
