Figure 6

Differential measurements of the stable (266 nm, left) and extremely unstable laser sources (1800 nm, right). (a,b) Ionization yields obtained using the 266 nm source at the first target NS (a) and at the second one NR (b) shown in Fig. 5. (c) Ionization yield modulation δN obtained using (a) and (b). Insets in (a) and (c) show the ionization yield modulation from −2 fs to 2 fs. (d,e) Ionization yields NS (d) and NR (e) obtained using the 1800 nm source. (f) Ionization yield modulation δN obtained using (d) and (e) (see Methods for the calculation of the ionization yield modulation).
