Book ChapterDOI
The One-Atom Maser and Cavity Quantum Electrodynamics
Gerhard Rempe,Herbert Walther +1 more
TL;DR: When a valence electron of an atom is excited in an orbit with high principal quantum number and therefore far from the ionic core, the energy levels of the atom can simply be described by the Rydberg formula.
Journal ArticleDOI
Micromaser spectrum and phase diffusion dynamics
Federico Casagrande,Alessandro Ferraro,A. Lulli,Rodolfo Bonifacio,Enrique Solano,Herbert Walther +5 more
TL;DR: In this article, a scheme to relate the phase diffusion dynamics of the micromaser field to the measured atomic population statistics is proposed, which can be used to solve a relevant decoherence problem in cavity quantum electrodynamics.
Journal Article
Absolute frequency measurement of the In+ clock transition with a mode-locked femtosecond laser
J. von Zanthier,Th. Becker,M. Eichenseer,A. Yu. Nevsky,Ch. Schwedes,Ekkehard Peik,Herbert Walther,Ronald Holzwarth,J. Reichert,Th. Udem,Theodor W. Hänsch,P. V. Pokasov,Mikhail N Skvortsov,S. N. Bagayev +13 more
TL;DR: In this article, the 5s 2 1 S 0 -5s5p 3 P 0 clock transition in a single trapped 115In+ ion at a wavelength of 237 nm was determined to 1 267 402 452 899.
Journal ArticleDOI
Dynamic control of micromaser and laser emission from driven three-level atoms
Tserensodnom Gantsog,Tserensodnom Gantsog,Georg M. Meyer,Georg M. Meyer,Georg M. Meyer,Marlan O. Scully,Marlan O. Scully,Herbert Walther,Herbert Walther +8 more
TL;DR: In this article, the master equations for the field in the micromaser and laser operating on three-level atoms driven by an external coherent field are presented, and exact solutions for the steady-state photon distributions are derived.
Journal ArticleDOI
Surface plasmons and photon statistics
TL;DR: In this paper, the statistical properties of photons emitted by decaying surface plasmons were studied by different methods, including time interval statistics, photon-number distribution and correlation function of the generated plasmon.
