Journal ArticleDOI
Generation of intense, carrier-envelope phase-locked few-cycle laser pulses through filamentation
Christoph P. Hauri,W. Kornelis,F.W. Helbing,A. Heinrich,Arnaud Couairon,André Mysyrowicz,Jens Biegert,U. Keller +7 more
TL;DR: In this article, a carrier-envelope offset (CEO) phase locked few-cycle pulses are generated using self-guiding of intense 43-fs, 0.84 mJ optical pulses during propagation in a transparent noble gas.
Journal ArticleDOI
Multi-octave supercontinuum generation from mid-infrared filamentation in a bulk crystal
Francisco Silva,Dane R. Austin,Alexandre Thai,Matthias Baudisch,Michael Hemmer,Daniele Faccio,Arnaud Couairon,Jens Biegert +7 more
TL;DR: This work presents an all-in-one solution, the first supercontinuum in a bulk homogeneous material extending from 450 nm into the mid-infrared, based on filamentation of femtosecond mid-Infrared pulses in the anomalous dispersion regime.
Journal ArticleDOI
Ultrafast electron diffraction imaging of bond breaking in di-ionized acetylene

TL;DR: Using mid-infrared laser–induced electron diffraction (LIED), the molecular structure of acetylene (C2H2) is imaged 9 femtoseconds after ionization and measurements are in excellent agreement with a quantum chemical description of field-dressed molecular dynamics.
Journal ArticleDOI

TL;DR: In this article, the authors presented a compact source that generates sub-two-cycle-duration pulses with an average power of 0.1μm and a spectral coverage of 6.8-16.4μm.
Journal ArticleDOI

TL;DR: Generation of 3.8-fs pulses with energies of up to 15 microJ from a supercontinuum produced in two cascaded hollow fibers is demonstrated through a closed-loop combination of a spatial light modulator for adaptive pulse compression and spectral-phase interferometry for direct electric-field reconstruction (SPIDER) measurements as feedback signal.
