Index of refraction of gases for matter waves: effect of the motion of the gas particles on the calculation of the index
Caroline Champenois, Marion Jacquey, Steven Lepoutre +3
Two different formulae relating the index of refraction of gases for atom waves to the scattering amplitude have been published. We show here that these two formulae are not co…
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…
Doppler cooling of calcium ions using a dipole-forbidden transition
R. J. Hendricks, J. L. Sørensen, C. Champenois +2
Doppler cooling of calcium ions has been experimentally demonstrated using the S1/2 to D5/2 dipole-forbidden transition. Scattering forces and fluorescence levels a factor of 5 sma…
Terahertz frequency standard based on three-photon coherent population trapping
Caroline Champenois, Gaetan Hagel, Marie Houssin +3
A scheme for a THz frequency standard based on three-photon coherent population trapping in stored ions is proposed. Assuming the propagation directions of the three lasers obey th…
