“…They demonstrated the first autocorrelation and FROG measurement of a single, sub-fs pulse ͑Sekikawa et Kosuge et al, 2006͒. Unfortunately, the relevant two-photon cross sections become prohibitively low toward shorter wavelengths ͑Nikolopoulos and 51 For a theoretical analysis, see Zhang et al, 2007. Lambropoulos, 2001͒, preventing straightforward extension of this metrology toward SXR frequencies. 55…”

Intense ultrashort light pulses comprising merely a few wave cycles became routinely available by the turn of the millennium. The technologies underlying their production and measurement as well as relevant theoretical modeling have been reviewed in the pages of Reviews of Modern Physics ͑Brabec and Krausz, 2000͒. Since then, measurement and control of the subcycle field evolution of few-cycle light have opened the door to a radically new approach to exploring and controlling processes of the microcosm. The hyperfast-varying electric field of visible light permitted manipulation and tracking of the atomic-scale motion of electrons. Striking implications include controlled generation and measurement of single attosecond pulses of extreme ultraviolet light as well as trains of them, and real-time observation of atomic-scale electron dynamics. The tools and techniques for steering and tracing electronic motion in atoms, molecules, and nanostructures are now becoming available, marking the birth of attosecond physics. In this article these advances are reviewed and some of the expected implications are addressed.

“…Subsequent studies show that the scaling law holds for both directly emitted and rescattered photoelectrons [14] in both long-pulsed [13] and few-cycle laser fields. [15] The scaling law of rescattered photoelectrons is of great importance, since the scaling law provides a necessary reference that can be used to classify different experimental results, by which the structure of targets is retrieved. Using the recently derived analytical formulae, [16] we find that, under the scaling transform, both the kinetic energy spectra and the PADs of rescattered photoelectrons remain unchanged.…”

By solving the time-dependent Schrödinger equation, the dependence of photoelectron energy spectra on the binding energy of targets, wavelength and the intensity of laser pulse is exhibited and a scaling law of kinetic energy spectra of both the direct and the rescattered photoelectrons is concluded. The scaling law provides a convenient tool to determine the equivalent photoionization process of various atoms or molecules in various laser fields. The verification of the scaling law by independent methods provides incontestable support to the validity of the scaling law.
