Table-top laser delivers intense extreme-ultraviolet light

Generating XUV pulses
High harmonics: a NIR pulse (red) is focussed, and high harmonics are generated in a gas jet that is placed before or behind the NIR focus. The generated XUV light (violet) has a size and divergence that are like the NIR beam. The process involves the multiple ionization of atoms in the gas, which is illustrated at the top of the figure.

The smallest source capable of delivering high-intensity pulses of extreme-ultraviolet (XUV) light h
