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 of how short-time dynamics can determine the electronic properties of more complex systems.

Attosecond light pulses are used for ultrahigh-resolution observations of ultrafast phenomena in atoms, molecules and condensed matter. Measuring the durations of such pulses is challenging because the spectrum lies in the vacuum ultraviolet or soft-X-ray range. This article reviews and compares two methods — photoionization and photorecombination — for measuring the duration of attosecond pulses.
