Laser cooling by coherent scattering inside an optical cavity, a method proposed for cooling the motion of arbitrary particles that scatter light, is analyzed in terms of the modified emission spectrum. In contrast to conventional Doppler cooling, this method invokes the two-photon Doppler effect along the direction of the momentum transferred in the scattering process. Three-dimensional coolin...

Laser cooling has led to spectacular results in recent years [1]. So far, however, it has not allowed to reach temperatures for which quantum statistics become important. In particular, evaporative cooling is used to obtain Bose-Einstein condensation of trapped gases [2]. Nevertheless, several groups are pursuing the challenging goal of condensation via all–optical means [3–5]. In traps of size...
