Attosecond science

Attosecond science is the study of processes that occur on a time scale of a few attoseconds (10-18 seconds) or less. Examples include the ionization and recollision of an electron from its parent atom or molecule. The speed of these phenomena means that they can only be investigated using optical techniques employing ultrafast lasers.
