Journal ArticleDOI
Strong-Field Tunneling without Ionization
TL;DR: In the tunneling regime of strong laser field ionization, a substantial fraction of neutral atoms surviving the laser pulse in excited states is measured, confirming the existence of a widely unexplored neutral exit channel (frustrated tunneling ionization).
Journal Article
Young`s interference experiment with light scattered from two atoms
TL;DR: In this paper, the first observation of interference in the light scattered from two trapped atoms localized in a linear Paul trap was reported, and the visibility of the interference fringes can be explained in the frame-work of Bragg scattering by a harmonic crystal, but with important differences compared to the case of a large crystal.
Journal ArticleDOI
Acceleration of neutral atoms in strong short-pulse laser fields
TL;DR: In this paper, the ponderomotive force on electrons is identified as the driving mechanism, leading to probably the highest observed acceleration on neutral atoms in an external field to date, with a magnitude as high as ∼1014 times the Earth's gravitational acceleration.
Journal Article
Acceleration of neutral atoms in strong short-pulse laser fields
TL;DR: The ponderomotive force on electrons is identified as the driving mechanism, leading to ultrastrong acceleration of neutral atoms with a magnitude as high as ∼1014 times the Earth’s gravitational acceleration, which is by far the highest observed acceleration on neutral atoms in external fields.
Journal ArticleDOI
Strong Laser Field Fragmentation of H 2 : Coulomb Explosion without Double Ionization
Bastian Manschwetus,Thomas Nubbemeyer,K. Gorling,Günter Steinmeyer,U. Eichmann,Horst Rottke,W. Sandner +6 more
TL;DR: It is argued that the recently investigated phenomenon of frustrated tunnel ionization is also at work in the neutralization of H+ ions into excited H atoms, resulting in fragmentation of H2 molecules exposed to strong laser fields into excited neutral atoms.
