Coherent light transport in a cold strontium cloud.
We study light coherent transport in the weak localization regime using magneto-optically cooled strontium atoms. The coherent backscattering cone is measured in the four polarization channels using light resonant with a J(g) = 0-->J(e) = 1 transition of the strontium atom. We find an enhancement factor close to 2 in the helicity preserving channel, in agreement with theoretical predictions. Th...

متن کاملSupplemental Material: Coherent scattering of near-resonant light by a Dense Microscopic Cold Atomic cloud
This Supplemental Material presents more details about the definition of the coherent transfer function S(ω) and the expressions of the laser field used in the modeling. It also derives the mean-field expression of the susceptibility for a multi-level alkali atom that we use in the Lorentz-Lorenz formula to calculate the field scattered by the cloud. Finally, we discuss the influence on the lin...
متن کاملCoherent Scattering of Near-Resonant Light by a Dense Microscopic Cold Atomic Cloud.
We measure the coherent scattering of light by a cloud of laser-cooled atoms with a size comparable to the wavelength of light. By interfering a laser beam tuned near an atomic resonance with the field scattered by the atoms, we observe a resonance with a redshift, a broadening, and a saturation of the extinction for increasing atom numbers. We attribute these features to enhanced light-induced...
متن کاملCoherent Backscattering of Light by Cold Atoms
Light propagating in an optically thick sample experiences multiple scattering. It is now known that interferences alter this propagation, leading to an enhanced backscattering, a manifestation of weak localization of light in such diffuse samples. This phenomenon has been extensively studied with classical scatterers. In this letter we report the first experimental evidence for coherent backsc...
