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
Observation of a Train of Attosecond Pulses from High Harmonic Generation
TL;DR: It is found that the harmonics are locked in phase and form a train of 250-attosecond pulses in the time domain, suggesting that Harmonic generation may be a promising source for attosecond time-resolved measurements.
Journal ArticleDOI
High-order harmonic generation in rare gases with a 1-ps 1053-nm laser.
Anne L'Huillier,Ph. Balcou +1 more
TL;DR: Results of harmonic generation using a 1-ps 1015-W/cm2 Nd-glass laser are presented and different ways of optimizing the number of photons by defocusing the laser beam or increasing the density are discussed.
Journal ArticleDOI
Dual optical tunneling times in frustrated total internal reflection
Ph. Balcou,L. Dutriaux +1 more
TL;DR: In this article, the optical tunneling times associated with frustrated total internal reflection of a light beam were investigated experimentally using as physical clocks the lateral shifts and angular deviations suffered by the transmitted and reflected beams.
Journal ArticleDOI
Global optimization of high harmonic generation.
Sophie Kazamias,Denis Douillet,F. Weihe,Constance Valentin,Antoine Rousse,Stéphane Sebban,G. Grillon,F. Augé,Daniele Hulin,Ph. Balcou +9 more
TL;DR: It is shown that harmonic generation in guided or freely propagating geometries are equivalent in the loose focusing regime and generalized to other advanced phase-matching schemes, thereby predicting the possibility to boost the conversion efficiencies using light noble gases.
