Journal ArticleDOI
Velocity selection for ultracold atoms using a micromaser
TL;DR: In this article, the authors proposed an atom-optical analog of a Fabry-Perot resonator, which allows for macroscopic coherence lengths and can narrow the velocity distribution of ultracold atoms passing through a resonant microwave cavity.
Journal ArticleDOI
Atom pairs in the micromaser
TL;DR: In this paper, it was shown that the so-called trapped vacuum state (in which single atoms would undergo a complete Rabi cycle while traversing the cavity and emerge without having emitted a photon) is destroyed even when more than 99% of the atoms participate in one-atom events.
Journal ArticleDOI
Spatial phase dislocations in femtosecond laser pulses
Kaloyan S. Bezuhanov,Alexander Dreischuh,Gerhard G. Paulus,Michael G. Schätzel,Herbert Walther,Dragomir N. Neshev,Wieslaw Krolikowski,Yuri S. Kivshar +7 more
TL;DR: In this paper, spatial phase dislocations associated with optical vortices are embedded in femtosecond laser beams by computer-generated holograms, provided that they are built in a setup compensating for the introduced spatial dispersion of the broad spectrum.
Journal ArticleDOI
Absolute frequency measurement of the In+ 5sS0–5s5pP0 transition
J. von Zanthier,J Abel,Th. Becker,M. Fries,Ekkehard Peik,Herbert Walther,Ronald Holzwarth,J. Reichert,Th. Udem,Theodor W. Hänsch,A. Yu. Nevsky,Mikhail N Skvortsov,S. N. Bagayev +12 more
TL;DR: In this article, the absolute frequency of the 115 In+ 5s 2 1 S 0 −5s5p 3 P 0 clock transition at 2365 nm with an accuracy of 33 parts in 1011 was measured.
Journal ArticleDOI
Intensity-intensity correlations as a probe of interferences under conditions of noninterference in the intensity
TL;DR: In this article, it was shown that in cases where the intensity interferences disappear the intensity-intensity correlations can display an interference pattern with a visibility of up to 100% depending on the polarization selected for the detection and is independent of the strength of the driving field.
