Journal ArticleDOI
Controlling the carrier-envelope phase of ultrashort light pulses with optical parametric amplifiers.
TL;DR: A white-light seeded optical parametric amplifier is suggested as a self-stabilized source of few-cycle pulses, in which the phase of the electric field is exactly reproduced in each laser shot.
Journal ArticleDOI
Visible pulse compression to 4 fs by optical parametric amplification and programmable dispersion control.
TL;DR: Angular dispersion of pump frequencies is shown to be an efficient mechanism for bandwidth enhancement in a noncollinear optical parametric amplifier and feedback for an iterative computer-controlled dispersion compensation algorithm is based on pulse characterization by second-harmonic generation frequency-resolved optical gating.
Journal ArticleDOI
Parametric amplification of few-cycle carrier-envelope phase-stable pulses at 2.1 μm
Takao Fuji,N. Ishii,Catherine Y. Teisset,Xun Gu,Thomas Metzger,Andrius Baltuška,Nicolas Forget,David L. Kaplan,Almantas Galvanauskas,Ferenc Krausz +9 more
TL;DR: An optical parametric chirped-pulse amplifier producing infrared 20 fs (3-optical-cycle) pulses with a stable carrier-envelope phase with well-suppressed background of parametric superfluorescence is demonstrated.
Journal ArticleDOI
Multimillijoule chirped parametric amplification of few-cycle pulses
N. Ishii,L. Turi,Vladislav S. Yakovlev,Takao Fuji,Ferenc Krausz,Andrius Baltuška,R. Butkus,G. Veitas,Valerijus Smilgevičius,Romualdas Danielius,A. Piskarskas +10 more
TL;DR: In this article, the concept of optical parametric chirped-pulse amplification is applied to attain pulses with energies up to 8 mJ and a bandwidth of more than 100 THz.
Journal ArticleDOI
Generation of sub-two-cycle mid-infrared pulses by four-wave mixing through filamentation in air.
Takao Fuji,Toshinori Suzuki +1 more
TL;DR: Fundamental and second-harmonic pulses of 25 fs Ti:sapphire amplifier output were focused into the air to produce extremely broadband mid-infrared pulses by four-wave difference-frequency generation through the filamentation to demonstrate sub-two-cycle, microjoule pulse generation.
