Abstract

We calculate and measure the magic wavelengths for the $6{s}^{2}^{1}S_{0}\ensuremath{-}6s6p\phantom{\rule{0.16em}{0ex}}^{3}P_{1}$ intercombination transition of the neutral ytterbium atom. The calculation is performed with the ab initio configuration interaction $+$ all-order method. The measurement is done with laser spectroscopy on cold atoms in an optical dipole trap. The magic wavelengths are determined to be 1035.68(4) nm for the $\ensuremath{\pi}$ transition $(\mathrm{\ensuremath{\Delta}}m=0)$ and 1036.12(3) nm for the $\ensuremath{\sigma}$ transitions $(|\mathrm{\ensuremath{\Delta}}m|=1)$ in agreement with the calculated values. Laser cooling on the narrow intercombination transition could achieve better results for atoms in an optical dipole trap when the trap wavelength is tuned to near the magic wavelength.

Abstract The static and dynamic electric dipole polarizabilities of the 6 s 2 1 S 0 and 6 s 6 p 3 P 1 o states of Yb are calculated by using the relativistic ab initio method. Focusing on the red detuning region to the 6 s 2 1 S 0 – 6 s 6 p 3 P 1 o transition, we find two magic wavelengths at 1035.7(2) and 612.9(2) nm for the 6 s 2 1 S 0 – 6 s 6 p 3 P 1 o , M J = 0 transition and three magic wavelengths at 1517.68(6), 1036.0(3) and 858(12) nm for the 6 s 2 1 S 0 – 6 <mm

Predicting magic wavelengths accurately requires precise knowledge of electric dipole matrix elements of nearby atomic transitions. As a result, measurements of magic wavelengths allow us to test theoretical predictions for the matrix elements that frequently cannot be probed by any other methods. Here, we calculate and measure a magic wavelength near 473 nm of the $5{s}^{2}\phantom{\rule{0.16em}{0ex}}^{1}{S}_{0}\ensuremath{-}5s5p\phantom{\rule{0.16em}{0ex}}^{3}{P}_{1}$ intercombination transition of $^{88}\mathrm{Sr}$ . Experimentally, we find 473.371(6) nm for $\mathrm{\ensuremath{\Delta}}m=0$ ($\ensuremath{\pi}$ transition) and 473.117(15) nm for $\mathrm{\ensuremath{\Delta}}m=\ensuremath{-}1$ (${\ensuremath{\sigma}}^{\ensuremath{-}}$ transition). Theoretical calculations yield 473.375(22) and 473.145(20) nm, respectively. Determining magic wavelengths nearby the dominant 461-nm probe transition of $^{88}\mathrm{Sr}$ holds promise for state insensitive interfacing of strontium atoms and nanophotonic devices with a narrow band of operating wavelengths. Furthermore, the $^{3}{P}_{1}$ polarizability is dominated by the contributions to the $5{p}^{2}\phantom{\rule{0.16em}{0ex}}^{3}P$ levels, and excellent agreement of theory and experiment validates both theoretical values of these matrix elements and estimates of their uncertainties.Predicting magic wavelengths accurately requires precise knowledge of electric dipole matrix elements of nearby atomic transitions.

Hyperfine constants and line separations for the S01−P13 intercombination line in neutral ytterbium with sub-Doppler resolution

Optical frequency measurements of the intercombination line $(6{s}^{2})\phantom{\rule{0.16em}{0ex}}^{1}S_{0}\ensuremath{-}(6s6p)\phantom{\rule{0.16em}{0ex}}^{3}P_{1}$ in the isotopes of ytterbium are carried out with the use of sub-Doppler fluorescence spectroscopy on an atomic beam. A dispersive signal is generated to which a master laser is locked, while frequency counting of an auxiliary beat signal is performed via a frequency comb referenced to a hydrogen maser. The relative separations between the lines are used to evaluate the $^{3}P_{1}$ -level magnetic dipole and electric quadrupole constants for the fermionic isotopes. The center of gravity for the $^{3}P_{1}$ levels in $^{171}\mathrm{Yb}$ and $^{173}\mathrm{Yb}$ are also evaluated, where we find significant disagreement with previously reported values. These hyperfine constants provide a valuable testbed for atomic many-body computations in ytterbium.Optical frequency measurements of the intercombination line $(6{s}^{2})\phantom{\rule{0.16em}{0ex}}^{1}S_{0}\ensuremath{-}(6s6p)\phantom{\rule{0.16em}{0ex}}^{3}P_{1}$ in the isotopes of ytterbium are carried out with the use of sub-Doppler fluorescence spectroscopy on an atomic beam.

We present measurements of three distinctive state-dependent wavelengths for the $^{1}S_{0}\text{\ensuremath{-}}^{3}P_{0}$ clock transition in ${}^{\text{174}}\text{Yb}$ atoms. Specifically, we determine two magic wavelengths at 652.281(21) and $542.502\phantom{\rule{0.16em}{0ex}}05(19)\phantom{\rule{0.16em}{0ex}}\text{THz}$ , where the differential light shift on the $^{1}S_{0}\text{\ensuremath{-}}^{3}P_{0}$ clock transition vanishes, and one tune-out wavelength at $541.8325(5)\phantom{\rule{0.16em}{0ex}}\text{THz}$ , where the polarizability of the $^{1}S_{0}$ ground state exhibits a zero crossing. The two magic wavelengths are identified by spectroscopically interrogating cold ${}^{\text{174}}\text{Yb}$ atoms on the clock transition in a one-dimensional optical lattice. The ground-state tune-out wavelength is determined via a parametric heating scheme.

Magneto-optical trapping of Yb atoms using an intercombination transition

剛桑本, T. Kuwamoto, 和仁本多 +5 more

We report the magneto-optical trapping of ytterbium atoms using the 6s2 1S0-6s6p 3P1 intercombination transition. The magneto-optical trap is continuously loaded from an atomic beam decelerated by a Zeeman-tuned atomic-beam slower operated at the 6s2 1S0-6s6p 1P1 transition. Among seven stable isotopes of ytterbium, six isotopes of 170Yb, 171Yb, 172Yb, 173Yb, 174Yb, and 176Yb are successfully trapped. The number and density of the trapped atoms are about 108 and 1011 cm-3, respectively. The temperature of atoms is estimated to be about 20 μK from the time-of-flight measurement. The decay time of the trapped atoms after stopping the loading of atoms is about 3 s.We report the magneto-optical trapping of ytterbium atoms using the 6s2 1S0-6s6p 3P1 intercombination transition.
