Compression of high-energy laser pulses below 5 fs
Mauro Nisoli,S. De Silvestri,Orazio Svelto,Robert Szipocs,K. Ferencz,Ch. Spielmann,S. Sartania,Ferenc Krausz +7 more
TL;DR: High-energy 20-fs pulses generated by a Ti:sapphire laser system were spectrally broadened to more than 250 nm by self-phase modulation in a hollow fiber filled with noble gases and subsequently compressed in a broadband high-throughput dispersive system, resulting in the shortest generated to date at multigigawatt peak powers.
Journal ArticleDOI
Femtosecond Optical Breakdown in Dielectrics
M. Lenzner,Jörg Krüger,S. Sartania,Zhao Cheng,Ch. Spielmann,Gerard Mourou,Wolfgang Kautek,Ferenc Krausz +7 more
TL;DR: In this article, the optical breakdown threshold and ablation depth in dielectrics with different band gaps for laser pulse durations ranging from 5 ps to 5 fs at a carrier wavelength of 780 nm.
Journal ArticleDOI
Generation of Coherent X-rays in the Water Window Using 5-Femtosecond Laser Pulses
Ch. Spielmann,N. H. Burnett,N. H. Burnett,S. Sartania,S. Sartania,R. Koppitsch,R. Koppitsch,M. Schnürer,M. Schnürer,C. Kan,C. Kan,M. Lenzner,M. Lenzner,P. Wobrauschek,P. Wobrauschek,Ferenc Krausz,Ferenc Krausz +16 more
TL;DR: In this article, an x-ray supercontinuum was generated at a repetition rate of 1 kilohertz by focusing 5-femtosecond near-infrared (780 nm) laser pulses into a helium gas jet.
Journal ArticleDOI
Amplitude and phase control of ultrashort pulses by use of an acousto-optic programmable dispersive filter: pulse compression and shaping.
TL;DR: It is demonstrated experimentally that an arbitrary phase and amplitude profile can be applied to an ultrashort pulse by use of an acousto-optic programmable dispersive filter (AOPDF) that has a large group-delay range and a 30% diffraction efficiency over 150 THz.
Journal ArticleDOI
Controlling the phase evolution of few-cycle light pulses
Alexander Apolonski,Andreas Poppe,Gabriel Tempea,Ch. Spielmann,Th. Udem,Ronald Holzwarth,Theodor W. Hänsch,Ferenc Krausz +7 more
TL;DR: Using a coherent nonlinear optical technique, slipping of the carrier through the envelope of 6-fs light wave packets emitted from a mode-locked-oscillator/pulse-compressor system has been measured, permitting the generation of intense, few-cycle light with precisely reproducible electric and magnetic fields.
