Kinetic phenomena of resonant-particle motion in a standing-light-wave field are theoretically discussed. The light-pressure force and its fluctuations are found in a wide range of the parameters: the atomic velocity, the intensity, and the detuning of the field. There are two characteristic regions of the detunings in a strong field: the adiabatic region and the region of Landau–Zener resonances. The quantum fluctuations of the inner atomic state that are due to the Landau–Zener transitions result, specifically, in the interference effect in the mean light-pressure force. The effects of the spatial grating of the cooled atoms, the particle velocity bunching, and the recoil-effect dependence on the nonlinear absorption are considered for slow particles. The effect of optical pumping by linearly polarized light taking into account the recoil effect is fundamentally new. Because of this effect, the anisotropic resonance medium becomes gyrotropic.

Control of atomic motion with resonant laser light is the most interesting field of research which is rapidly expanding. The book discusses the latest theoretical and experimental achievements in the study of these phenomena. The fundamental questions of the theory of resonant light pressure are given in the book. They are: 1. Optical Stern-Gerlach Effect and Quantization of Atomic Motion in a Light Field; 2. Theory of Light Pressure Force and Atomic Kinetics in a Strong Field; 3. Diffraction and Interference of Atoms; 4. Velocity Bunching Effect, Cooling and Localization of Atoms in Light Field, and 5. Polarization Phenomena and Recoil Effect. The most important experiments are also discussed in this book. While the book may be used to get a primary acquaintance with the subject, specialists will also find the latest theoretical and experimental results and achievements in this field discussed here.

The influence of the resonance light pressure on the motion of atoms and molecules is studied. A kinetic equation has been obtained describing the action on particles of both the mean force of light pressure and its fluctuations. The forces that are considered are due to spontaneous and stimulated transitions and also to a certain combination thereof. The kinetic equation is used to describe the scattering of atoms in conditions close to the experimental ones [16]. The temperature of atoms cooled in a standing wave with the aid of the force of light pressure of the combined type has also been found.
