Physicists are now producing attosecond laser pulses that are short enough to probe atomic and subatomic electron processes. Rob van den Berg spoke to Ferenc Krausz and Reinhard Kienberger, two pioneers in attosecond physics, about their work. 2021-01-29 Recent progress in sub-laser-cycle gating of high-order harmonic generation promises to push the limits on optical pulse durations below the atomic unit of time, 24 as, which corresponds to a bandwidth broader than 75 eV. However, the available techniques for attosecond pulse measurement are valid only for narrow-bandwidth spectra, due to one of the key approximations made in the phase retrieval.

A laser light shines in a gas cell where UCF researchers generate attosecond pulses. Courtesy: UCF. Studies of ultrafast processes could become more widely accessible thanks to researchers at the University of Central Florida (UCF) in the US, who have shown that commercially available, industrial-grade lasers can generate attosecond pulses of light.

For light compression, Chini says, researchers commonly use self-phase modulation in noble-gas-filled An The Attosecond Laser Facility (ALFA) is a cutting-edge attosecond laser light source user facility in Japan. The planning and preparation of ALFA is currently being carried out by the Consortium for Attosecond Laser Science and Technology (COAST), which was established in April, 2017, at the University of Tokyo.

Ferenc Krausz from the Max Planck Institute of Quantum Optics in Munich is considered the founder of attosecond physics.

In order to to do attosecond research we need record-breaking short laser pulses and make use of the pump-probe technique. We use two synchronised laser pulses with a precisely controlled time-delay to record movies of electrons in motion. Ferenc Krausz from the Max Planck Institute of Quantum Optics in Munich is considered the founder of attosecond physics. His goal is to develop new laser tec The CFEL-ATTO group collaborated in experiments aimed at controlling the ionization of LiNbO 3 with strong-field lasers, gaining new insights on the role of microscopic material properties in this fundamental process through femtosecond laser-ablation, a technique often employed in high-resolution micromachining of materials.

Welcome to my personal website. I am interested in attosecond science and the enabling laser technology. Attosecond science aims to look at dynamics of electrons in real time. Electrons move inside atom and molecules on a timescale of attoseconds. The units 1 attosecond (1 as) corresponds to 10^-18 seconds. An incredibly short time. One attosecond is to…

Tuesday 9 Jun 2015, 10:00 → 11:00​  Here we report the generation of isolated GW-scale soft X-ray attosecond pulses with an X-ray free-electron laser.

When an attosecond light pulse passes through a material, the interaction with electrons in the When atoms interact with strong laser fields, high-order harmonics are generated. In the time domain, this radiation consists of ultrashort "attosecond" light pulses with central photon energy in the extreme ultraviolet (XUV) energy domain and duration of the order of 100 as. Attosecond science consists in generating attosecond pulses and in using Attosecond science works somewhat like sonar or 3D laser mapping, but at a much smaller scale.
