Journal ArticleDOI
Field-free orientation of CO molecules by femtosecond two-color laser fields.
Sankar De,Irina Znakovskaya,Dipanwita Ray,Fatima Anis,Nora G. Johnson,Irina Bocharova,Maia Magrakvelidze,B. D. Esry,C. L. Cocke,Igor Litvinyuk,Matthias F. Kling +10 more
TL;DR: The demonstrated method can be applied to study molecular frame dynamics under field-free conditions in conjunction with a variety of spectroscopy methods, such as high-harmonic generation, electron diffraction, and molecular frame photoelectron emission.
Journal ArticleDOI
Attosecond tracing of correlated electron-emission in non-sequential double ionization
Boris Bergues,Matthias Kübel,Nora G. Johnson,Nora G. Johnson,B. Fischer,Nicolas Camus,K. J. Betsch,K. J. Betsch,O. Herrwerth,Arne Senftleben,A. Max Sayler,A.

TL;DR: The experimental results and the proposed semiclassical model provide strong constraints for the development of theories and lead us to revise common assumptions about the mechanism that governs double ionization.
Journal ArticleDOI
Review of attosecond resolved measurement and control via carrier–envelope phase tagging with above-threshold ionization
Tim Rathje,Tim Rathje,Nora G. Johnson,Max Möller,Frederik Süßmann,D. Adolph,Matthias Kübel,Reinhard Kienberger,Matthias F. Kling,Gerhard G. Paulus,A. M. Sayler,A. M. Sayler +11 more
TL;DR: In this article, a real-time, single-shot carrier-envelope phase (CEP) tagging technique for few-cycle pulses was developed and combined with cold-target recoil-ion momentum spectroscopy and velocity-map imaging to investigate and control CEP-dependent processes with attosecond resolution.
Journal ArticleDOI
Single-shot carrier-envelope-phase-tagged ion-momentum imaging of nonsequential double ionization of argon in intense 4-fs laser fields
Nora G. Johnson,O. Herrwerth,Adrian Wirth,Sankar De,Itzik Ben-Itzhak,Matthias Lezius,Boris Bergues,Matthias F. Kling,Arne Senftleben,C. D. Schröter,R. Moshammer,Joachim Ullrich,K. J. Betsch,Robert Jones,A. M. Sayler,T. Rathje,Klaus Rühle,Walter M. Müller,Gerhard G. Paulus +18 more
TL;DR: In this paper, single-shot carrier-envelope-phase (CEP) tagging is combined with a reaction mircoscope (REMI) to investigate CEP-dependent processes in atoms.
Journal ArticleDOI
Attosecond Correlated Dynamics of Two Electrons Passing through a Transition State
Nicolas Camus,B. Fischer,M. Kremer,Vandana Sharma,Artem Rudenko,Boris Bergues,Matthias Kübel,Nora G. Johnson,Matthias F. Kling,Thomas Pfeifer,Joachim Ullrich,R. Moshammer +11 more
TL;DR: The strong-field induced decay of a doubly excited, transient Coulomb complex Ar**→Ar(2+)+2e(-) is explored by tracing correlated two-electron emission in nonsequential double ionization of Ar as a function of the carrier-envelope phase.
