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. We characterize individual attosecond pulses, including their instantaneous frequency, and identify double pulses with well-defined delays and spectral properties, thus paving the way for X-ray pump/X-ray probe attosecond free-electron laser science. Attosecond interferometry in time-energy domain. The space-momentum domain interferometer is a key technique in modern precision measurements, and has been widely used for applications that Researchers make attosecond-scale measurements by passing an attosecond light pulse through a material.

For context, an attosecond is to a second what a second is to about 31.71 billion years. The word "attosecond" is formed by the prefix atto and the unit second.

Attosecond Science ª Real time observation of electron dynamics in matter We develop advanced attosecond technologies to investigate the light-activated dynamics of matter with extreme time resolution. The Lund Attosecond Science Center (LASC) combines three collaborating research groups: Attosecond Physics: From lasers to applications (Groupleaders: Cord Arnold, Anne L'Huillier) Attosecond XUV Spectroscopy (Groupleader: Johan Mauritsson) Intense XUV Attosecond Physics (Groupleader: Per Johnsson) The aim of LASC is to study dynamics of matter and for the rst time measure pulses shorter than one femtosecond (1 fs = 10 15 s), so called attosecond (1 as = 10 18 s) pulses [1]. With these pulses the possibility to do attosecond time-resolved measurements opened up. Since electron dynamics take place on this time scale, the advent of attosecond pulses meant 2020-06-02 · Tabletop attosecond light sources in the soft X-ray (SXR) spectral region based on high-harmonic generation are highly desirable in chemical and material sciences since they can spectroscopically Generating stable optical waveforms and measuring them with (sub-)attosecond temporal accuracy and single-photon sensitivity will enable spectroscopy at its fundamental limits.

When an attosecond light pulse passes through a material, the interaction with electrons in the 2020-09-17 “The Frontiers of Attosecond and Ultrafast X-ray Science” Erice, Sicily, Italy: March 10-16, 2019. PURPOSE OF THE COURSE. The new millennium witnessed two revolutionary breakthroughs in ultrafast x-ray science. In 2001, two independent groups reported the formation of attosecond pulses of XUV radiation. 2014-06-10 2020-06-17 Quantum Physics with Attosecond Pulses” (QPAP) is the name of a project supported by an ERC-grant which has started in January.
