We describe the recent emergence of attosecond science, assessing the present state of the art and discussing several recent examples where attosecond electron dynamics has been studied in atomic and molecular systems. After introducing the generation and characterization of attosecond laser pulses, we describe the use of isolated attosecond pulses in a pump-probe experiment revealing the

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 - one An attosecond (as) is a very short period of time. It is equal to one quintillionth of a second (or 0.000000000000000001 seconds). It can also be written as 10−18 seconds. An attosecond (as) is a unit of time that equals one quintillionth of a second, or 10 to the 18th power. To put the attosecond in the context of the speed of light, one attosecond allows light to travel the length of three hydrogen atoms. An electron transfers between two atoms in about 320 attoseconds. An attosecond is one quintillionth (10 -18) of a second and is a term used in photon research.
Temporal information can be obtained either by pump-probe techniques or by phase and amplitude measurements over a large spectral range. 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.
