Generating UV from a light-speed mirror

A laser pulse (red, bottom), liberates electrons (green) from the carbon atoms of a nanometer-thin foil and accelerates them to close to the speed of light. An infrared light pulse impinges on the electron layer from the opposite direction and reflects off the electron mirror as a light burst in the extreme ultraviolet with a duration of only a few hundred attoseconds. Image: Thorsten Naeser.

Researchers succeed in generating flashes of extreme ultraviolet radiation via the reflection from a mirror that moves close to the speed of light.
