We report a detailed study of the enhanced optical molasses cooling of Cs atoms, whose large hyperfine structure allows to use the largely red-detuned cooling lasers. We find that the combination of a large frequency detuning of about− 110 MHz for the cooling laser and a suitable control for the powers of the cooling and repumping lasers allows to reach a cold temperature of∼ 5.5 μK. We obtain 5.1× 10 7 atoms with the number density around 1× 10 12 cm− 3. Our result gains a lower temperature than that got in other experiments, in which the cold Cs atoms with the temperature of∼ 10 μK have been achieved by the optical molasses cooling.
