Fig. 1 (a) The three-step model of HHG.5 Ionization (by tunneling through the Coulomb + laser field potential, blue arrow) launches an electron in the continuum, which is subsequently accelerated by the oscillatory NIR laser field. Along some of the trajectories (red arrow), the electron returns to the ionic core, and a recombination accompanied by the emission of coherent XUV/X-ray light Controlling attosecond angular streaking with second harmonic radiation T.

Corkum1 1Joint Attosecond Science Laboratory, University of Ottawa and National Research Council of Canada, 100 Sussex Dr, Noun 1. attosecond - one quintillionth of a second; one thousandth of a femtosecond time unit, unit of time - a unit for measuring time periods femtosecond It is well established that electrons can escape from atoms through tunneling under the influence of strong laser fields, but the timing of the process has been controversial and far too rapid to probe in detail. We used attosecond angular streaking to place an upper limit of 34 attoseconds and an intensity-averaged upper limit of 12 attoseconds on the tunneling delay time in strong field Attosecond science refers to physical processes that occur on the natural timescale of electron motion in atomic and molecular systems. Attosecond time resolution can be obtained experimentally through a process called high-order harmonic generation where sharp attosecond pulses are formed in the time domain. 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 10−24, 1 yoctosecond, ys, Yoctosecond, (yocto- + second), is one 10−18, 1 attosecond, as, One quintillionth of one second, 12 attoseconds: shortest Put more picturesquely, one attosecond compares to one second approximately as one second to the age of the universe.

2018-07-16 · The continuous spectrum in the HHG cutoff region is selected by a metallic filter to obtain a single attosecond pulse, which is recombined with a small part of the NIR pulse and focused onto the second target (gas or solid). The attosecond XUV pulses first ionize the second target to produce photoelectrons, and then the photoelectrons are shifted in the momentum space by an amount that depends on the vector potential of the NIR field at the time when the XUV and IR pulses overlap

The researchers directed an attosecond-long, extremely ultraviolet (XUV) light pulse onto a helium atom to excite the electrons. At the same time, they fired a second infrared laser pulse at the
Light travels 0.3 nanometers in an attosecond, which is roughly the spacing between atoms in a solid.

first attosecond light pulses were created by the interaction of strong laser fields with gaseous, atomic targets11,12. One attosecond is staggeringly short, 1 as = 10-18 seconds, and one attosecond compares to one second in the way one second compares to the age of the universe. The timescale
The word "attosecond" is formed by the prefix atto and the unit second. The shortest pulses produced to date are under 60 attoseconds, i.e..
