Radiative collimation of an atomic beam by two-dimensional cooling by a laser beam
Balykin V. I., Letokhov V. S. , Sidorov A. I.
Two-dimensional radiative cooling of a beam of sodium atoms by radiation-pressure forces has been studied in an axisymmetric standing light wave. The temperature of the transverse motion of the atoms was reduced to 3.5 mK.
