Large Faraday rotation of resonant light in a cold atomic cloud
During the past 2 yr, we have been theoretically and experimentally investigating coherent backscattering ~CBS! of near-resonant light in a sample of cold rubidium atoms @1–3#. CBS is an interference effect in the multiple scattering regime of propagation inside random media, yielding an enhancement of the backscattered light intensity @4#. This interference is very robust and can be destroyed ...
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 کاملSlow diffusion of light in a cold atomic cloud.
We study the diffusive propagation of multiply scattered light in an optically thick cloud of cold rubidium atoms illuminated by a quasiresonant laser beam. In the vicinity of a sharp atomic resonance, the energy transport velocity of the scattered light is almost 5 orders of magnitude smaller than the vacuum speed of light, reducing strongly the diffusion constant. We verify the theoretical pr...
