Resonance laser spectroscopy of ion pairs in a Nd^3+: LaF_3 crystal

Ахмеджанов Ринат Абдулхаевич, A. A. Bondartsev, Л. А. Гущин +1 more

This paper shows that the satellite lines that appear in the absorption and fluorescence spectra of neodymium ions in a LaF3 crystal at concentrations of about 0.5 at.% and the accompanying lines of the isolated ion are caused by pairwise interaction of the Nd3+ ions. Double optical resonance is used to study the structure of the satellite lines in the neighborhood of the 4I9/2→4G5/2 transition of the isolated ion (wavelength 5777.1 Å), hidden by inhomogeneous broadening. When neodymium ion pairs are excited by resonance laser radiation, the presence of anti-Stokes components is recorded in the fluorescence spectrum (up-conversion). It is shown that the main up-conversion mechanism is cumulative pair excitation. These results are convincing evidence that the suppression of absorption from excited levels can be experimentally observed in condensed media.

Linear Trap for High-accuracy Spectroscopy of Stored Ions

Mark G. Raizen, Jonathan Magnolia Gilligan, Jonas Bergquist +2 more

In a linear r.f. Paul trap, ‘crystallized’ structures of laser-cooled 199Hg+ ions are observed. The ground-state hyperfine transition at 40·5 GHz is observed in microwave-optical double-resonance spectroscopy. Future prospects are also discussed.

Ionic crystals in a linear Paul trap

Mark G. Raizen, Jonathan Magnolia Gilligan, Jonas Bergquist +2 more

We describe a configuration for a linear Paul rf ion trap. This trap can store a long string of ions with a small second-order Doppler shift, comparable to that achieved with a single ion in a quadrupole Paul trap. Crystallized strings of trapped ions, as well as more complicated structures, have been observed in the trap. We report an observation of the 40.5-GHz ground-state hyperfine interval of $^{199}\mathrm{Hg}^{+}$ by microwave-optical double-resonance spectroscopy and discuss prospects for a microwave frequency standard based on a trapped string of ions.
