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.

    High-order harmonics in the extreme-ultraviolet regime can be produced and a stable waveform-locked attosecond pulse can be formed when quartz is excited by a strong short-pulsed laser, providing a robust path towards attosecond photonics.

    Without a very precise timer one can never catch up with the electron released in photoemission. Attosecond streaking spectroscopy allows such a chronometer clock to be set to zero and reveals the role of electron correlations.
