Attosecond physics: An easier route to high harmony

Mark I. Stockman1

The generation of ultrashort light pulses by atomic ionization and recombination doesn't come cheap. But by niftily exploiting the play of light on a nanostructured surface, it can be done on a table-top.

Extreme ultraviolet (EUV) radiation has great potential to be extreme not just in name, but in usefulness. It is the band of ultraviolet light with the shortest wavelength — around 5–50 nanometres, between 100 and 10 times shorter than that of visible light.
