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
bandwidth radiation, whereas the shortest laser pulses are ~1fs as seen in the time scale to the left. Attosecond light pulses are an important scientific advance

The experimental methods aim at the characterization and manipulation of bulk media, nanostructures, quantum-confined structures and interfaces on the attosecond time scale. Examples include: Harmonic concatenation; Transient absorption and dispersion spectroscopy with miniature beamlines 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.
When atoms interact with strong laser fields, high-order harmonics are generated.
The researchers first prepared a hydrogen molecular ion by using a ‘pump’ pulse from an attosecond laser to eject an electron from a neutral hydrogen molecule. This process set the molecular ion vibrating. The team then used a ‘probe’ attosecond pulse to split the vibrating molecular ion into two parts—a hydrogen atom (a proton and
Laser physics: Attosecond photoelectron spectroscopy accelerated Date: February 5, 2019 Source: Ludwig-Maximilians-Universität München Summary: Laser physicists have succeeded in reducing the However, the energy limitation of these lasers supports only weak sources and correspondingly linear attosecond studies. Here we report on an optical parametric synthesizer designed for nonlinear attosecond optics and relativistic laser-plasma physics. laser needs to be synchronous to the ionization event on a time scale below that of the process to be resolved.

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.
When an attosecond light pulse passes through a material, the interaction with electrons in the material distorts the pulse. Attosecond science works somewhat like sonar or 3D laser mapping, but at a much smaller scale. When an attosecond light pulse passes through a material, the interaction with electrons in the material distorts the pulse. The observation and manipulation of electron dynamics in matter call for attosecond light pulses, routinely available from high-order harmonic generation driven by few-femtosecond lasers. However http://www.weforum.org/ Toward Attosecond Science with Workaday Lasers On-hand technology. Being a leader in the attosecond field “has always required access to the best lasers,” says Chini. Compressing light.

18 Apr 2006. Physicists are now producing attosecond laser pulses that are short enough to probe atomic and subatomic electron processes.
We study the energy transfer from a strong infrared (IR) laser field to the ionized electrons as a function of the delay between the XUV and IR fields. Our study can be regarded as an initial approximation of attosecond laser–particle interaction when the prevalent phenomenon is photon–electron interaction. The electrons interact with the laser beam, which means that the nucleus does not play a significant role in temperature distribution.
