In Bohr’s model of the hydrogen atom, it takes 150 attoseconds for the electron in the ground state to complete one cycle of revolution. Some other processes in atoms and molecules can be even faster. Attosecond pulses of light can provide the resolution needed for studying and ultimately controlling the attosecond dynamics of electrons.  Therefore, there is a strong scientific demand for the development of sources of high-energy, attosecond pulses.

In this lecture, (i) 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.
