Bragg scattering of optical pulses from localized atoms in one-dimensional optical lattices

John A. Vaccaro, Karen E. Hill, Alan V. Durrant

We outline the theory of a practical Bragg scattering technique for studying the long-range spatial order of atoms localized in one-dimensional optical lattices and we demonstrate the technique using and F = 1 → 1 transitions with lin ⊤ lin laser cooling fields. The latter transition gives a dark optical lattice. We show that the scattering by a spin grating, which may also be present, can be completely or partially filtered out by varying the polarizations of the cooling fields while holding the polarization of the probe and the detector analyser fixed. This allows the fraction of atoms that are localized to be measured. The probe field is treated as a pulse and so the technique also allows time-resolved details of the spatial structure to be studied.

Dimensional crossover in Bragg scattering from an optical lattice

Sebastian Slama, C. von Cube, A. Ludewig +3 more

We study Bragg scattering at one-dimensional (1D) optical lattices. Cold atoms are confined by the optical dipole force at the antinodes of a standing wave generated inside a laser-driven high-finesse cavity. The atoms arrange themselves into a chain of pancake-shaped layers located at the antinodes of the standing wave. Laser light incident on this chain is partially Bragg reflected. We observe an angular dependence of this Bragg reflection which is different from what is known from crystalline solids. In solids, the scattering layers can be taken to be infinitely spread (three-dimensional limit). This is not generally true for an optical lattice consistent of a 1D linear chain of pointlike scattering sites. By an explicit structure factor calculation, we derive a generalized Bragg condition, which is valid in the intermediate regime. This enables us to determine the aspect ratio of the atomic lattice from the angular dependance of the Bragg scattered light.

Self-induced Bragg-type scattering in dark optical superlattices

Péter Horák, Helmut Ritsch

We show that the coherent part of the atomic fluorescence spectrum in a dark optical superlattice can be interpreted as a new type of Bragg scattering of the trapping lasers by the periodic atomic distribution. We explicitly solve the 1D problem to demonstrate that this built-in mechanism provides a diagnostic tool to determine the atomic position and energy distribution without any extra disturbance of the system. Hence, in principle, this method allows one to gain important information on atom-atom interactions and quantum statistics in the case of several atoms confined within a single optical (super)well.
