Real time interferometric manipulation of a neutral atomic beam by electric field

Abstract

Electric-field-controlled holography for atoms is demonstrated. Platinum electrodes are deposited among the array of parallel slits that are made on a silicon nitride film. A cold neon atomic beam in the 1s3[2p5(2Po1/2)3s : J = 0] metastable state is sent through the film and form a Fraunhofer diffraction pattern on a microchannel plate detector that is placed in the downstream of the film. By controlling the potential of each electrode an arbitrary one-dimensional diffraction pattern of atoms has been generated.PACS No. 78.90

Phase controlled atom holography

Fujio Shimizu, Jun‐ichi Fujita, S. Mitake

Summary form only given. We have demonstrated the manipulation of a cold neon atomic beam in a metastable state by using a silicon nitride thin film with holes that expressed the pattern of a binary hologram. The atoms that passed through the computer generated binary hologram reconstructed an arbitrary pattern of atoms on the surface of a microchannel plate detector. In this paper we describe the technique that enables us to control the reconstructed pattern in real time. We deposited regularly spaced stripes of platinum electrodes on the thin film hologram. Holes were open in the gap between the stripes, and we modulated the electric potential of the electrodes. This modulated the phase of the atom that passed through the hole in proportion to the square of the potential difference of the adjacent electrodes. Two types of phase controlled holography were demonstrated.

Interferometric Modulation of an Atomic Beam by an Electric Field: A Phase Hologram for Atoms

Jun‐ichi Fujita, S. Mitake, Fujio Shimizu

Electric-field-controlled atomic holography has been demonstrated. A binary hologram pattern was encoded in the gaps of regularly spaced parallel stripes of platinum electrodes formed on SiN4 thin film. Each electrode was either grounded or connected to a terminal. The electrode connections were arranged so that an electric field appeared in approximately half the 512 gaps when a finite voltage was applied to the terminal. By controlling this voltage, we could shift, erase, or switch holographically reconstructed two-dimensional images of atoms on a screen.

Wave Front Control and Atomic Wave Holography

Jun‐ichi Fujita

We describe various techniques to manipulate laser-cooled Ne atoms interferometrically by using a silicon nitride film with holes and electrode deposition. Laser-cooled Ne atoms pass through a computer-generated through-hole binary hologram and generate an atomic image on a substrate. The hologram can be designed to provide a spherical phase correction, and the reconstructed pattern is focused on the substrate at a finite distance from the hologram. Such holographic manipulation can be extended to gray-scaled reconstruction that is used to deposit relief-like 3D atomic patterns on surfaces. In addition, an atom interacts with electric, magnetic, and optical fields. This provides the holographic atomic-wave manipulation to perform functions that are difficult for a light wave. The Stark shift induced by an external electric field is used to switch and to modify atomic patterns in real time. We also introduce an reflecting type atom holography by using quantum reflection.

Reflection-Type Hologram for Atoms

Fujio Shimizu, Jun‐ichi Fujita

A cold metastable neon atomic beam was manipulated with a reflective amplitude hologram that was encoded on a silicon surface. A black-and-white pattern of atoms was reconstructed on a microchannel plate detector. The hologram used the enhanced quantum reflection developed by authors and was made of a two-dimensional array of rectangular low and high reflective cells. The surface of the high reflective cell was composed of regularly spaced roof-shaped ridges, while the low reflective cell was simply a flat surface. The hologram was the first demonstration of reflective atom-optical elements that used universal interaction between a neutral atom and solid surface.

Atom interferometers and atom holography

Fujio Shimizu, Jun‐ichi Fujita, Makoto Morinaga +2 more

Various techniques of atom manipulation with a binary hologram are discussed and demonstrated experimentally. An atomic beam of metastable neon in the 1s3 state and a SiN thin film with holes that expresses the transmission function of the hologram are used to demonstrate this technique. The gray-scale holography of atoms is demonstrated for the first time. Other possibilities of holographic manipulation of atoms are also discussed.

Holographic Manipulation of a Cold Atomic Beam

A method of generating an arbitrary pattern of atoms by using an interferometric technique is reported. A laser-cooled metastable Ne atomic beam in the ${1s}_{3}$ state is diffracted by a computer generated binary hologram. A black-and-white pattern is drawn on a microchannel detector with a spatial resolution exceeding $65\ensuremath{\mu}\mathrm{m}$ and a resolving power better than $30$.
