Westudyhowthescattering properties of laser driven atoms are modified by the presence of an optical resonator.This investigation can be divided into two parts. First, we study the scaling of the scatteringproperties with the number of atoms, and we show in particular how Bragg scattering by anatomiclattice ismodifiedbythepresenceoftheresonator. Inthiscase, theatoms aretrappedatthe antinodes of the cavity mode function bythe mechanical potential induced bythe resonator.In a second part, we show how this modification of the scattering properties can be used forefficientlycoolingsingleatomstothegroundstateofaharmonictrap.
