Attosecond time resolution can be obtained experimentally through a process called high-order harmonic generation where sharp attosecond pulses are formed in
An attosecond is 10-18 seconds, or 0.0000000000000000001 seconds. These timescales are so small they are in fact comparible to ATTO2021 - 8th Int.

It can also be written as 10−18 seconds. An attosecond is one billionth of a billionth of a second, and the ability to make measurements with attosecond precision allows researchers to study the fast motion of electrons inside atoms and Attosecond pulses, the shortest light flashes that human beings have been able to achieve, provide a unique tool for deeply exploring insights into the microworld with real-time observation. 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. Capturing the underlying (Color) Attosecond streaking spectrogram of an XUV pulse, recorded with a few-cycle streaking field. The streak images exhibit little broadening at any timing, indicating that the XUV pulse is near Fourier limited and is much shorter than T L ∕ 2. As a consequence, one does not need to know its detailed structure to determine E L (t).

Quantum Physics with Attosecond Pulses” (QPAP) is the name of a project supported by an ERC-grant which has started in January. Here the background and a description of the goals of the project will be given. This is a Mötesplats Rydberg seminar, arranged by Department of Physics every Tuesday.
Details When atoms interact with strong laser fields, high-order harmonics are generated . In the time domain, this radiation consists of ultrashort "attosecond" light The emphasis of the research in the last 20 years is in the scientific areas of AMO physics, attosecond science and strong field laser-matter interactions.

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. This lecture was a part of 59th international scientific conference for students of physics and natural sciences "Open Readings 2016".

Definition of attosecond. : one quintillionth (10−18) of a second An attosecond is to a second what a second is to the age of the universe. — IEEE Spectrum.
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. Achieving that requires pushing technology to produce pulses using higher-wavelength sources, and also producing pulses that encompass a wider range 1 attosecond: as One quintillionth of one second 12 as: best timing control of laser pulses. 43 as: shortest laser pulse: 10 −15: 1 femtosecond: fs One quadrillionth of one second 1 fs: Cycle time for 300-nanometre light; ultraviolet light; light travels 0.3 micrometres (µm).
