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 0.1-TW 5-fs optical pulses at a 1-kHz repetition rate.
TL;DR: In this paper, a compact all-solid-state femtosecond Ti:sapphire oscillator-amplifier system using no grating-based pulse stretcher produces 20-fs, 1.5mJ pulses at a 1-kHz repetition rate.
Journal ArticleDOI
Laser ablation of dielectrics with pulse durations between 20 fs and 3 ps
TL;DR: In this article, a Ti sapphire laser system at a wavelength of 780 nm was used for ablation in a borosilicate glass with an extremely high glass transformation temperature (∼600°C).
Journal ArticleDOI
A novel-high energy pulse compression system: generation of multigigawatt sub-5-fs pulses
Mauro Nisoli,Salvatore Stagira,S. De Silvestri,Orazio Svelto,S. Sartania,Zhao Cheng,M. Lenzner,Christian Spielmann,Ferenc Krausz +8 more
TL;DR: In this article, the spectral broadening by propagation along hollow-core fused silica fiber filled with atomic and molecular gases is studied under two excitation regimes with high-energy input pulses of 140 fs and 20 fs duration respectively.
