This thesis reports an experimental study of the modifications of the near-resonant light scattering properties of mesoscopic cold clouds of rubidium 87 which densities are tunable. for densities of the order of 1014 atoms/cm3, inter-atomic distances can be smaller than the wavelength of the radiation at resonance with the d2 line (780 nm) of rubidium 87. the magnitude of the dipole-dipole interactions between the scatters is such that they can no longer be considered as independent of each other: a phenomenon called collective scattering. the methods used to produce the studied samples are based on cooling (zeeman slower and magneto-optical trap) and trapping (optical tweezers) techniques for neutral atoms. they allow obtaining cold (100 µ...
