53-attosecond X-ray pulses reach the carbon K-edge
The motion of electrons in the microcosm occurs on a time scale set by the atomic unit of time—24 attoseconds. Attosecond pulses at photon energies corresponding to the fundamental absorption edgesExpand

Attosecond time-resolved autoionization of argon.
Autoionization of argon atoms was studied experimentally by transient absorption spectroscopy with isolated attosecond pulses. The peak position, intensity, linewidth, and shape of the 3s3p⁶np ¹PExpand

Sub-cycle Oscillations in Virtual States Brought to Light
We probe the transient changes in the absorption of an isolated attosecond extreme ultraviolet (XUV) pulse by helium atoms in the presence of a delayed, few-cycle near infrared (NIR) laser pulse, which uncovers absorption structures corresponding to laser-induced “virtual” intermediate states in the two-color two- and three-photon absorption process.

Subcycle ac stark shift of helium excited states probed with isolated attosecond pulses.
Recent advances in attosecond science have relied upon the nearly instantaneous response of free electrons to an external field. However, it is still not clear whether bound electrons are able toExpand

Single attosecond pulse and xuv supercontinuum in the high-order harmonic plateau
It is proposed that single attosecond pulses be generated by gating high-order harmonic emission with fields whose ellipticity varies rapidly with time. The laser pulse with a time-dependentExpand

Effects of orbital symmetries in dissociative ionization of molecules by few-cycle laser pulses
We have measured angular distributions of ion fragments produced in dissociative double ionization of CO, CO{sub 2}, and C{sub 2}H{sub 2} by intense ultrashort laser pulses. This report extendsExpand

What will it take to observe processes in 'real time'?
Even for simple systems, the interpretations of new attosecond measurements are complicated and provide only a glimpse of their potential. Nonetheless, the lasting impact will be the revelation ofExpand
