Laser locking to the 199Hg clock transition with 5.4x10^(-15)/sqrt(tau) fractional frequency instability
J. J. McFerran, D. V. Magalhaes, C. Mandache +5
With Hg atoms confined in an optical lattice trap in the Lamb-Dicke regime, we obtain a spectral line at 265.6 nm in which the full-width at half-maximum is <15Hz. Here we lock an…
An Ultra-Stable Referenced Interrogation System in the Deep Ultraviolet for a Mercury Optical Lattice Clock
S. T. Dawkins, R. Chicireanu, M. Petersen +5
We have developed an ultra-stable source in the deep ultraviolet, suitable to fulfill the interrogation requirements of a future fully-operational lattice clock based on neutral me…
Ultrastable lasers based on vibration insensitive cavities
J. Millo, D. V. Magalhaes, C. Mandache +7
We present two ultra-stable lasers based on two vibration insensitive cavity designs, one with vertical optical axis geometry, the other horizontal. Ultra-stable cavities are const…
Doppler-free spectroscopy of the 1S0-3P0 optical clock transition in laser-cooled fermionic isotopes of neutral mercury
M. Petersen, R. Chicireanu, S. T. Dawkins +5
We have performed for the first time direct laser spectroscopy of the 1S0-3P0 optical clock transition at 265.6 nm in fermionic isotopes of neutral mercury laser-cooled in a magnet…
Cold Atom Clocks, Precision Oscillators and Fundamental Tests
S. Bize, P. Wolf, M. Abgrall +17
We describe two experimental tests of the Equivalence Principle that are based on frequency measurements between precision oscillators and/or highly accurate atomic frequency stand…
A Search for Variations of Fundamental Constants using Atomic Fountain Clocks
H. Marion, F. Pereira Dos Santos, M. Abgrall +12
Over five years we have compared the hyperfine frequencies of 133Cs and 87Rb atoms in their electronic ground state using several laser cooled 133Cs and 87Rb atomic fountains with…
