In situ sub-50 attosecond active stabilization of the delay between infrared and extreme ultraviolet light pulses

Martin Luttmann, David Bresteau, Jean-François Hergott +2

The blooming of attosecond science (1 as = $10^{-18}$ s) has raised the need to exquisitely control the delay between two ultrashort light pulses, one of them being intense and in…
