Comment on "Prospect of optical frequency standard based on a 43Ca+ ion"
Caroline Champenois, Martina Knoop, Marie Houssin +3
A recent evaluation of the frequency uncertainty expected for an optical frequency standard based on a single trapped Ca ion was published in Phys. Rev. A {\bf 72} (2005…
Long-term stabilization of the length of an optical reference cavity
Gaëtan Hagel, Marie Houssin, Martina Knoop +3
To obtain a high degree of long-term length stabilisation of an optical reference cavity, its free-spectral range is locked by means of an accurate and stable frequency synthesizer…
Dark resonances as a probe for the motional state of a single ion
C. Lisowski, M. Knoop, C. Champenois +3
Single, rf-trapped ions find various applications ranging from metrology to quantum computation. High-resolution interrogation of an extremely weak transition under best observatio…
Evaluation of the ultimate performances of a Ca+ single-ion frequency standard
Caroline Champenois, Marie Houssin, Caroline Lisowski +4
We numerically evaluate the expected performances of an optical frequency standard at 729 nm based on a single calcium ion. The frequency stability is studied through the Allan dev…
Metastable level lifetimes from electron-shelving measurements with ion clouds and single ions
Martina Knoop, Caroline Champenois, Gaëtan Hagel +4
The lifetime of the 3d^2D_5/2-level in singly-ionized calcium has been measured by the electron-shelving technique on different samples of rf trapped ions. The metastable state has…
