Abstract

One-color two-photon excitation spectra of the 7F05D0 and 7F05D2 transitions of Sm2+ in SrF2 have been measured at low temperature and their dependences upon photon polarization analyzed. Linewidths on the order of 0.2, 0.6, and 1.0 cm-1 are obtained for the 7F05D0(A1g), 7F05D2(Eg), and 7F05D2(T2g) Stark components observed at 15 K, respectively. The 7F05D0(A1g) transition is observed to be isotropic within experimental error, while the Eg and T2g components of the 7F05D2 transition exhibit the anisotropic patterns expected in Oh symmetry. Calculations of two-photon transition intensities are conducted within the framework of the phenomenological model previously used for Sm2+ in MClF (M=Ba,Sr) and Eu3+ in LuPO4, where the rare-earth ion occupies sites of C4v and D2d symmetries, respectively. The present results are compared and contrasted with those obtained in these previous cases.
