Scattering of an atom near a mirror to form a standing light wave field

V. A. Grinchuk, I. A. Grishina, E. F. Kuzin +3 more

In this paper we present some new results concerning the observed anomalous frequency properties of the process of the neutral atom scattering in the standing light wave field near the reflecting mirror. The investigations were carried out using the method of scattering of the sodium atomic strip beam, intersecting at right angle the region of the standing light wave field. The standing light wave field was formed by two counterpropagating waves of resonant laser radiation -- incident and reflected from the mirror, mounted at a distance of about 1 cm from the atomic beam. The coherence length of the laser radiation was about 10 cm, that's why the interaction of atoms with the field of two counterpropagating light waves was coherent. The width of the strip atomic beam (a equals 0.02 cm) was much less than the distance to the mirror. The specific feature of the given setup is the use of pulsed laser radiation with the duration (tau) less than 1/(gamma) ((gamma) -1- the time of resonant level spontaneous decay), so the atoms are scattered only due to the induced light pressure force. In this paper the detailed investigation of the distance R influence on the scattering process was carried out. With this purpose the mirror was mounted at different distances from the atomic beam.

Bragg Scattering from Atoms in Optical Lattices

G. Birkl, M. Gatzke, Ivan Deutsch +2 more

We observe coherently enhanced reflection (Bragg scattering) of a near resonant laser beam from cesium atoms ordered by a periodic array of optical potential wells known as an optical lattice. The reflected light is enhanced by a factor of $\ensuremath{\sim}{10}^{5}$ over scattering from a disordered atomic sample. We measure the magnitude of the reflectivity and its detuning dependence as functions of the density and the degree of localization of the atoms. The change in lattice constant due to the frequency-dependent effective index of refraction seen by the lattice light field is observed.

Bragg Scattering of Slow Atoms from NaStanding Light Wave

Gerhard Rempe, S. Kunze, Stephan Dürr

Slow atoms from a magneto-optical trap are used to study difiraction from a near-resonant standing-wave light fleld. Long interaction times make it possible to observe unidirectional Bragg scattering. In particular, the Pendellosung interference efiect between two resonant momentum states is demonstrated for flrst- and second-order difiraction. The oscillation frequency of second-order scattering shows a transition from a four-photon{type process at low light intensity to a two-photon{type process at higher intensity. The data are in quantitative agreement with a theoretical description which takes into account lowest-energy momentum states.
