Atom holography

TL;DR

This paper explores using atomic condensates as recording media for holography, proposing a reading scheme with atomic beams, and analyzing how condensate properties affect resolution and recording quality.

Contribution

It introduces a novel approach to atomic holography, detailing conditions for effective recording and reconstruction using condensates and atomic reading beams.

Findings

Good recording achieved with flat condensate profiles and negative detunings.

Resolution depends on the relation between healing length and optical spatial frequencies.

Proposed scheme enables object reconstruction via atomic reading beams.

Abstract

We study the conditions under which atomic condensates can be used as a recording media and then suggest a reading scheme which allows to reconstruct an object with atomic reading beam. We show that good recording can be achieved for flat condensate profiles and for negative detunings between atomic Bohr frequency and optical field frequency. The resolution of recording dramatically depends on the relation between the healing length of the condensate and the spatial frequency contents of the optical fields involved.
