Journal ArticleDOI
Plasma perspective on strong field multiphoton ionization.
TL;DR: During strong-field multiphoton ionization, a wave packet is formed each time the laser field passes its maximum value, and one important parameter which determines the strength of these effects is the rate at which the wave packet spreads in the direction perpendicular to the laser electric field.
Journal ArticleDOI
Theory of high-harmonic generation by low-frequency laser fields.
TL;DR: A simple, analytic, and fully quantum theory of high-harmonic generation by low-frequency laser fields is presented and the exact quantum-mechanical formula for the harmonic cutoff that differs from the phenomenological law Ip+3.17Up is presented.
Journal ArticleDOI
Tomographic imaging of molecular orbitals
Jiro Itatani,J. Levesque,J. Levesque,D. Zeidler,Hiromichi Niikura,Hiromichi Niikura,Henri Pépin,Jean-Claude Kieffer,Paul B. Corkum,David M. Villeneuve +9 more
TL;DR: It is demonstrated that the full three-dimensional structure of a single orbital can be imaged by a seemingly unlikely technique, using high harmonics generated from intense femtosecond laser pulses focused on aligned molecules.
Proceedings Article
Attosecond Metrology
TL;DR: The demonstrated experimental tools and techniques open the door to attosecond spectroscopy of bound electrons by using a subfemtosecond soft-X-ray pulse and a few-cycle visible light pulse to trace electronic dynamics with a time resolution of ≤ 150 as.
Journal ArticleDOI
High harmonic interferometry of multi-electron dynamics in molecules
Olga Smirnova,Yann Mairesse,Yann Mairesse,Serguei Patchkovskii,Nirit Dudovich,Nirit Dudovich,David M. Villeneuve,Paul B. Corkum,Misha Ivanov,Misha Ivanov +9 more
TL;DR: These findings establish high harmonic interferometry as an effective approach to resolving multi-electron dynamics with sub-Ångström spatial resolution arising from the de Broglie wavelength of the recombining electron, and attosecond temporal resolution arisen from the timescale ofThe recombination event.
