Abstract
Techniques to slowand t rap neutral atoms at high d ensities with r adiative forces are discussed in this review article. It isshown that the radiative force on an atomic system has two components, one coming from the rnomentum transferred from the photon to the atom and the other resul ting f rom the interaction of the transi t ion d i po 1 e mo- ment with the radiation field gradient. Among several methods of laser cooling, we emphasize Zeeman tuning of the electronic l evels and fre- quency-sweeping techniques. Trapping of neutral atoms is ano ther i n- teresting subject discussed in this review. We present recent resul ts obtained in light and magnetic traps. Finally, techniques to f urther c001 atoms inside traps a re presented and the future of laser cool i ng of neutral atoms by means of radiation pressure is discussed.
