Atom Optics

David E. Pritchard

A large-aperture liquid-He coated spherical mirror and a room-temperature bent-gold crystal have been used to focus atom beams of H and He, respectively. They are described elsewhere in this symposium. Many of the new optical elements for atoms rely on the mechanical forces of light; mirrors are one example. When atoms approach the surface of glass that has intense blue-detuned light inside, they recoil from the evanescent wave that extends several wavelengths past the surface and into the vacuum. The atoms are never close enough to the surface to be affected by its atomic attraction or its small-scale irregularities. When a highly collimated beam of sodium atoms is directed at a standing wave of light near its resonance frequency, the angular scattering pattern of the atoms exhibits the characteristics of diffraction from a short sinusoidal grating. Diffraction orders up to ~20 have been observed at high light intensities. In contrast to phase gratings made with light, material absorption gratings are amplitude gratings.A large-aperture liquid-He coated spherical mirror and a room-temperature bent-gold crystal have been used to focus atom beams of H and He, respectively.

Observation of Kapitza–Dirac Diffraction in Atomic Lithium Gas Using Bragg’s Scattering

V V Baturo, Vyacheslav Afanasievich Vinogradov, M. V. Platonova +2 more

A short-lived density grating is produced in a gas of lithium atoms. The gas is preliminarily cooled in a magnetooptical trap. The grating is formed due to diffraction of atoms on a standing light wave. The grating is observed from Bragg’s scattering of light from it. This method of formation and observation over the grating can be used in a lithium-based atomic interferometer.
