Control of Atomic Collisions by Laser Polarization

Abstract

Atomic collision pairs in a light field form a microscopic interferometer. The light acts as the beam splitter and controls at the same time the amplitudes and phases of the interfering waves. We demonstrate the complete tunability using linear and elliptic polarization.

Atom interferometry with polarizing beam splitters

H. Hinderthür, Andreas Pautz, F. Ruschewitz +2 more

A special kind of atomic beam splitter using a four-level atomic system in combination with polarized light fields is demonstrated. These specific atom optical elements are used to operate an atom interferometer where the beam-splitting mechanism acts selectively on specific paths only and therefore allows for several different interferometer geometries. Based on a Ramsey-Bord\'e configuration, the experimental data show considerably better accuracy and a contrast enhanced by 65% compared to the two-level interferometer. Our concept appears to be especially interesting in the context of metrological aspects in matter-wave interferometry.

Six-beam optical lattice with intrinsically stable time phases

Arno Rauschenbeutel, Harald Schadwinkel, V. Gomer +1 more

Summary form only given.To manipulate atomic motion by laser radiation in two or three dimensions, atoms are usually exposed to several laser beams whose interference pattern results from the light-atom interaction and hence the atom dynamics. In general, the resulting light field crucially depends on the relative phases of the interfering light beams. One method to provide a laser field with a stable intensity and polarization configuration is to reduce the number of beams.

Atom interferometers

J. Lone, K. Sengstock, Wolfgang A. Ertmer

Summary form only given.Atom interferometers have opened up new areas of fundamental and applied research. As well known from photon optics, multiple-beam interferometers offer an increased sensitivity on the relative phases between interfering waves. Very recently, first atomic multiple-beam interferometers were realized. These concepts are based on an atomic beam that is spatially split into coherent partial de Broglie waves, where the number of interfering waves is determined by the internal atomic multi-level scheme. We report on time-domain atomic interferometry within a two-level system.

Analysis and manipulation of atomic and molecular collisions using laser light

A. Grimpe

Optical collisions in a crossed beam experiment are examined for the atomic collision pairs LiHe, LiNe, NaNe.Differential cross sections are measured in order to probe the quallity of quantum chemical calculated and spectroscopical determined molecular potentials.The linear polarization of the excitation laser is used to manipulate the contrast of the differential cross sections for NaNe.Using elliptical polarized light total control over the angular position and the contrast of the interference pattern is demonstrated.Differential cross sections for the collision pairs LiH and LiD show a pronounced oscillatory structure, which for the first time is observed for atom-molecule optical collisions.
