Sub-femtosecond photon or electron pulses were both achieved within the past few years. The technology combines aspects of collision and optical physics. Experience teaches that the ability to make measurements in any new time regime opens new areas of science. In the case of attosecond pulses, the importance is not only "attoseconds", but the promise of combining sub-Angstrom spatial resolution with sub-femtosecond temporal precision (Attoseconds&Angstroms). I will describe how attosecond photon and electron pulses are produced and measured, emphasizing the common issues linking them. I will also show how electrons and photons combine to image electronic orbitals. (click here for webcast) |
