Dark Optical Lattice of Ring Traps for Cold Atoms
Emmanuel Courtade, Olivier Houde, Jean-François Clément +2
We propose a new geometry of optical lattice for cold atoms, namely a lattice made of a 1D stack of dark ring traps. It is obtained through the interference pattern of a standard G…
Manipulation of ultracold atomic mixtures using microwave techniques
D. Ciampini, E. Courtade, C. Sias +5
We used microwave radiation to evaporatively cool a mixture of of 133Cs and 87Rb atoms in a magnetic trap. A mixture composed of an equal number (around 10^4) of Rb and Cs atoms in…
A broadband Ytterbium-doped tunable fiber laser for 3He optical pumping at 1083 nm
Genevieve Tastevin, Sebastien Grot, Emmanuel Courtade +2
Large amounts of hyperpolarized 3He gas with high nuclear polarization rates are required for use in neutron spin filters or nuclear magnetic resonance imaging of human lung. Very…
Magnetic Field Effects on the 1083 nm Atomic Line of Helium. Optical Pumping of Helium and Optical Polarisation Measurement in High Magnetic Field
E. Courtade, F. Marion, P. -J. Nacher +3
The structure of the excited S and P triplet states of He and He in an applied magnetic field B is studied using different approximations of the atomic Ha…
