Field Compensation of Field Frequency Shifts in the Ramsey Spectroscopy of Clock Optical Transitions
A. V. Taichenachev, V. I. Yudin, C. W. Oates +2
We develop the method of Ramsey spectroscopy with the use of an additional field compensating the frequency shifts of clock optical transitions. This method in combination with the…
Frequency evaluation of the doubly forbidden transition in bosonic Yb
N. Poli, Z. W. Barber, N. D. Lemke +11
We report an uncertainty evaluation of an optical lattice clock based on the transition in the bosonic isotope Yb by use of magnetically induced…
Optical Lattice Induced Light Shifts in an Yb Atomic Clock
Z. W. Barber, J. E. Stalnaker, N. D. Lemke +6
We present an experimental study of the lattice induced light shifts on the 1S_0-3P_0 optical clock transition (v_clock~518 THz) in neutral ytterbium. The ``magic'' frequency, v_ma…
Direct excitation of the forbidden clock transition in neutral 174Yb atoms confined to an optical lattice
Zeb W. Barber, Chad W. Hoyt, Chris W. Oates +3
We report direct single-laser excitation of the strictly forbidden (6s^2)^1S_0 -(6s6p)^3P_0 clock transition in the even 174Yb isotope confined to a 1D optical lattice. A small (~1…
Magnetic field-induced spectroscopy of forbidden optical transitions with application to lattice-based optical atomic clocks
A. V. Taichenachev, V. I. Yudin, C. W. Oates +3
We develop a method of spectroscopy that uses a weak static magnetic field to enable direct optical excitation of forbidden electric-dipole transitions that are otherwise prohibiti…
The optical calcium frequency standards of PTB and NIST
U. Sterr, C. Degenhardt, H. Stoehr +7
We describe the current status of the Ca optical frequency standards with laser-cooled neutral atoms realized in two different laboratories for the purpose of developing a possible…
