The ground-state electron in the hydrogen atom completes one cycle of
revolution in 150 attoseconds. Some other processes in atoms and molecules are
even faster. Attosecond pulses of light can provide the resolution needed for
studying and ultimately controlling the attosecond dynamics of electrons in
atoms and molecules. Therefore, there is a strong scientific demand for the
development of sources of high-energy, attosecond pulses.
In this talk, I will (i) review the characteristic time and length scales in
atoms, molecules and nanostructures, (ii) outline the progress on short-pulse
generation over time and the state-of-the-art of production of high-energy,
ultrashort pulses; (iii) give some examples of attosecond processes in atoms,
(iv) discuss in detail novel concepts for the production of attosecond pulses
using electron bunches moving through periodic magnetic fields created by the
magnetic devices called undulators.
