A method of stably trapping, cooling, and manipulating atoms on a continuous-wave basis is proposed using resonance radiation pressure forces. Use of highly focused laser beams and atomic beam injection should give a very deep trap for confining single atoms or gases at temperatures \ensuremath{\sim} ${10}^{\ensuremath{-}6}$ \ifmmode^\circ\else\textdegree\fi{}K. An analysis of the saturation properties of radiation pressure forces is given.

The basic scattering and gradient forces of laser radiation pressure on atoms, dielectric particles, and biological particles are introduced, and experimental demonstrations of these forces are reviewed. As uses for radiation pressure forces, we consider the slowing, cooling, and trapping of neutral atoms at low temperatures; and the trapping and manipulation of dielectric and living biological particles in the Mie and Rayleigh size regimes.
