The absolute rotation measurement of atom interferometer by phase modulation

Zhu Chang-Xing, Feng Yan-Ying, Xiongying Ye +4 more

In the paper，a measurement method of absolute rotation of atom interferometer is proposed. Generally，there are π/2-π-π/2 phase gratings in an atom interferometer in the space domain. We add three special phases to the three gratings，then，we modulate the special phases to change the detector signal of atom interferometer，and Fourier transform is performed on the detector signal，to obtain the absolute rotation of atom interferometer. The results are the discussed in the paper.

Atom Wave Interferometry with Diffraction Gratings of Light

Ernst Maria Rasel, Markus K. Oberthaler, Herman Batelaan +2 more

We have developed a novel interferometer for atom de Broglie waves, where amplitude division and recombination is achieved by diffraction at standing light waves operating as phase gratings. Our new atom interferometer is the exact mirror image of interferometers for light, with the roles of atoms and photons interchanged, and it directly demonstrates coherence of the diffraction of atomic waves at standing light waves. Easy manipulation of the phase, intensity, and polarization of the standing light wave permits novel studies of atomic coherence properties.

An interferometer for atoms

David W. Keith, Christopher R. Ekstrom, Q. A. Turchette +1 more

We have demonstrated an interferometer for atoms. A three-grating geometry is used, in which the interfering beams are distinctly separated in both position and momentum. We used a highly collimated beam of sodium atoms with a de Broglie wavelength of 16 pm and high-quality 0.4-\ensuremath{\mu}m-period free-standing gratings which we fabricated using a novel method. The interference signal is 70 counts/s, which allows us to determine the phase to 0.1 rad in 1 min. Applications of atom interferometers are briefly discussed.
