Non-linear Spectroscopy of Sr Atoms in an Optical Cavity for Laser Stabilization
Bjarke T. R. Christensen, Martin R. Henriksen, Stefan A. Schäffer +4
We study the non-linear interaction of a cold sample of strontium-88 atoms coupled to a single mode of a low finesse optical cavity in the so-called bad cavity limit and investigat…
Observation of Motion Dependent Nonlinear Dispersion with Narrow Linewidth Atoms in an Optical Cavity
Philip G. Westergaard, Bjarke T. R. Christensen, David Tieri +5
As an alternative to state-of-the-art laser frequency stabilisation using ultra-stable cavities, it has been proposed to exploit the non-linear effects from coupling of atoms with…
Lattice Induced Frequency Shifts in Sr Optical Lattice Clocks at the Level
Philip G. Westergaard, Jérôme Lodewyck, Luca Lorini +5
We present a comprehensive study of the frequency shifts associated with the lattice potential for a Sr lattice clock. By comparing two such clocks with a frequency stability reach…
Minimizing the Dick Effect in an Optical Lattice Clock
Philip G. Westergaard, Jerome Lodewyck, Pierre Lemonde
We discuss the minimization of the Dick effect in an optical lattice clock. We show that optimizing the time sequence of operation of the clock can lead to a significant reduction…
An Optical Lattice Clock with Spin-polarized 87Sr Atoms
Xavier Baillard, Mathilde Fouché, Rodolphe Le Targat +14
We present a new evaluation of an 87Sr optical lattice clock using spin polarized atoms. The frequency of the 1S0-3P0 clock transition is found to be 429 228 004 229 873.6 Hz with…
Accuracy Evaluation of an Optical Lattice Clock with Bosonic Atoms
Xavier Baillard, Mathilde Fouché, Rodolphe Le Targat +6
We report the first accuracy evaluation of an optical lattice clock based on the 1S0 - 3P0 transition of an alkaline earth boson, namely 88Sr atoms. This transition has been enable…
