Hyper-Ramsey Spectroscopy of Optical Clock Transitions
V. I. Yudin, A. V. Taichenachev, C. W. Oates +6
We present non-standard optical Ramsey schemes that use pulses individually tailored in duration, phase, and frequency to cancel spurious frequency shifts related to the excitation…
Collisional losses, decoherence, and frequency shifts in optical lattice clocks with bosons
Ch. Lisdat, J. S. R. Vellore Winfred, T. Middelmann +2
We have quantified collisional losses, decoherence and the collision shift in a one-dimensional optical lattice clock with bosonic 88Sr. The lattice clock is referenced to the high…
Compensation of Field-Induced Frequency Shifts in Ramsey Spectroscopy of Optical Clock Transitions
A. V. Taichenachev, V. I. Yudin, C. W. Oates +6
We have extended Ramsey spectroscopy by stepping the probe frequency during the two Ramsey excitation pulses to compensate frequency shifts induced by the excitation itself. This m…
