Light scattering by a 1D chain of cold atoms
Light scattering by ordered atomic arrays has attracted a growing attention lately. Ordering the sample allows indeed to obtain strong cooperative response from the atomic dipoles and could allow to engineer collective effects beyond what can be obtained from the individual atomic response. In this talk I will present the efforts undertaken on our rubidium setup at Institut d’Optique in Palaiseau to induce a strong cooperative response by ordering an atomic ensemble. In particular we create a half-filled one dimensional chain of atoms by loading a tightly focused optical lattice from a magneto-optical trap using collisional blockade. We are performing first experiments to evidence a cooperative response in light scattering.
