In this paper the fastest electronic relaxation dynamics ever measured has been observed by attosecond transient-absorption spectroscopy (ATAS) at the carbon K-edge. Attosecond science The motion of electrons on the atomic scale has been hidden from direct experimental access until recently. We review the revolution in technology that opened the door to real-time observation and time-domain control of atomic-scale electron dynamics, and address the expected implications of 2019-01-21 · Likewise, the realm of attosecond science [6, 7] emerged when the attosecond (1 as =10 −18 s) time scale was reached by chirped-pulse amplification and high-harmonic generation (HHG) . Attosecond pulses have opened the possibilities to image and control the behaviour of electron wave packets within atoms.

In 2001, two independent groups reported the formation of attosecond pulses of XUV radiation. Since that time the field of attosecond science has grown exponentially and new attosecond laboratories have emerged throughout the world. Many experimental techniques that address the Wigner time delay employ two or more interfering pathways. For single-photon ionization, one such scheme is the reconstruction of attosecond harmonic beating by interference of two-photon transitions (RABBITT) 21. In RABBITT, there are two pathways that lead to the same final electron energy.

This control enables a gas of atoms to produce intense VUV or soft X-ray beams.

The behaviour of atoms in powerful laser fields is the key to attosecond science. Although this behaviour has been studied for many years, it is still not completely understood. We use the simplest atoms of all, hydrogen atoms, to make precise measurements of attosecond dynamics. 2019-01-21 On the other hand, those nonlinear processes in the XUV region is indispensable for progress of attosecond science including attosecond atomic/molecular physics and chemistry, because it is very useful for investigating ultrafast phenomena directly in attosecond time scale. 2010-04-16 2021-01-29 Attosecond Science Group cfel-atto.

This research was 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) Attosecond science also known as attophysics is a branch of Atomic, molecular, and optical physics wherein attosecond (10 −18 s) duration pulses of electrons or photons are used to probe dynamic processes in matter with unprecedented time resolution. An attosecond is 1×10 −18 of a second (one quintillionth of a second). 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. Atto-was derived from the Danish word for eighteen (atten). Its symbol is as.
