Manifestation of the resonance radiation pressure in a gas

Abstract The influence of the radiation pressure effect on the behavior of two-level gas in a field of a traveling quasi-resonance electromagnetic wave has been studied. The peak formation in the distribution function in a collisionless gas and the gas cooling in a collisional gas are shown.

Laser Cooling of Recombining Electron-Ion Plasma

A method of producing and confining ultracold electron-ion plasma with a strongly nonideal ion subsystem is considered. The method is based on the laser cooling of plasma ions by the radiation resonant with the ion quantum transition. A model is developed for the laser cooling of recombining plasma. Computer simulation based on this model showed that the ion nonideality parameter can be as large as ∼100. The data obtained demonstrate that the production of ultracold nonideal plasma is quite possible.

Laser control of the state of a plasma in a selective optical trap

Laser cooling of resonant ions is shown to be applicable to the effective control of the temperature of charged particles in a low-temperature electron-ion plasma confined in a magnetic trap.

Optical confinement of low-temperature plasma with resonant ions

Applications of the rectification of a gradient force in interfering bichromatic fields produced by intersecting laser beams for selective optical confinement of low-temperature electron-ion plasma with resonant ions are examined.

Optimal control of resonance radiation processes

Abstract Optimal control methods are applied to solve some quantum electronics problems. Some specific problems involving a two-level system state control by optimal resonance radiation pulse shapes are considered.

Confinement of Atoms with Nondegenerate Ground States in a Three-Dimensional Dissipative Optical Superlattice

Based on the developed kinetic theory of rectified radiative forces, we found sufficient conditions for purely optical (nonmagnetic) three-dimensional confinement and cooling of atoms with the J=0 → J=1 quantum transition in a weak field of mutually orthogonal bichromatic standing waves. We show that a deep stable atom localization of atoms in the cells of an effective light superlattice (with a spacing much larger than the light wavelength) can be achieved by controlling the phase shifts (time-difference phase) of the temporal oscillations in orthogonally polarized field components and by specially choosing the field parameters. The proposed scheme of purely optical confinement can be directly used for a large group of atoms like Yb isotopes and alkali-earth elements with even-even nuclei.

Manifestation of the gas translational nonequilibrium in a resonance electromagnetic field

Abstract The translational nonequilibrium of the resonance impure gas in a field of a traveling electromagnetic wave produced by both the radiation pressure and the difference in cross-sections of elastic collisions between the excited- and ground-state atoms and a buffer gas has been studied.

RESONANCE LASER ACTIONS AS AN EFFICIENT METHOD FOR CONTROL OF THE GAS AND PLASMA STATES

The results obtained by the authors in studies of the mechanical action of resonance laser light on gas and plasma are briefly reviewed.

Effects of the interaction between an optical membrane and plasma

A model is considered for the interaction with plasma of an “optical membrane” formed by bichromatic intersecting laser beams. This model is used to describe a number of effects resulting from the mechanical action of light on resonant ions in the plasma.

Laser cooling and Wigner crystallization of rarefied plasma

For the first time the optical method of electron-ion plasma cooling, trapping and crystallizing (on microscale) due to laser radiation action on plasma with resonant ions is proposed.
