Precision measurement of light shifts at two off-resonant wavelengths in a single trapped Ba+ ion and determination of atomic dipole matrix elements
J. A. Sherman, A. Andalkar, W. Nagourney +1
We define and measure the ratio (R) of the vector ac-Stark effect (or light shift) in the 6S_1/2 and 5D_3/2 states of a single trapped barium ion to 0.2% accuracy at two different…
Studies of the S--P transition in atomic ytterbium for optical clocks and qubit arrays
Tao Hong, Claire Cramer, Eryn Cook +2
We report an observation of the weak S-P transition in Yb as an important step to establish Yb as a primary candidate for future optical frequency…
Progress on indium and barium single ion optical frequency standards
Jeff A. Sherman, William Trimble, Steven Metz +2
We report progress on 115In+ and 137Ba+ single ion optical frequency standards using all solid-state sources. Both are free from quadrupole field shifts and together enable a searc…
Optical clocks based on ultra-narrow three-photon resonances in alkaline earth atoms
Tao Hong, Claire Cramer, Warren Nagourney +1
A sharp resonance line that appears in three-photon transitions between the and states of alkaline earth and Yb atoms is proposed as an optical frequency st…
