Two-step Doppler cooling of a three-level ladder system with an intermediate metastable level
Caroline Champenois, Gaetan Hagel, Martina Knoop +4
Doppler laser cooling of a three-level ladder system using two near-resonant laser fields is analyzed in the case of the intermediate level being metastable while the upper level i…
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…
