A general approach for optically controlled spatial structuring of overdense plasmas
generated at the surface of initially plain solid targets is presented. We demonstrate it …

The interaction of ultra-intense laser pulses with matter opened the way to generate the
shortest light pulses available nowadays in the attosecond regime. Ionized solid surfaces …

Energy coupling during relativistically intense laser–matter interactions is encoded in the
attosecond motion of strongly driven electrons at the pre-formed plasma–vacuum boundary …

High order harmonics generated at relativistic intensities have long been recognized as a
route to the most powerful extreme ultraviolet pulses. Reliably generating isolated …
