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. For comparison, a millisecond (ms or msec) is one thousandth of a second and is commonly used in measuring the time to read to or write from a hard disk or a CD-ROM player or to measure packet travel time on the Internet. To understand the movements of electrons, and eventually those of subatomic particles, requires attaining the attosecond and ultimately zeptosecond (sextillionths of a second) range, Kaertner says.

Methods Laser system: In our experiment, laser wavelengths of 1.3 and 2 μm are generated in a three-stage OPA seeded by a white-light continuum. Just as femtosecond pulses allow the observation of the motion of atoms in molecules, attosecond pulses will allow us to trace electronic motion and electronic relaxation (such as inner-shell dynamics) in atoms and molecules. In addition, attosecond science will have strong, phased laser fields perfectly synchronized with the attosecond pulse. “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.

For those unfamiliar, this process can generally be described by the "three step model": 2011-02-16 Attosecond science Corkum, P. B.; Krausz, Ferenc; Abstract. 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 2019-08-26 A novel scheme for generating a pair of gigawatt attosecond pulses by coherent Thomson scattering from relativistic electron sheets is proposed.

Attosecond optical pulse generation, along with the related process of high-order harmonic generation, is redefining ultrafast physics and chemistry. A practical 

Noun 1. 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).

2020-11-30 · The subcycle interaction of light and electrons has been one of the key frontiers in free-electron lasers, attosecond science and dynamical investigation of matter.
