Figure 2. Time-dependent photoelectron holography.

(a) Normalized difference S(t₁, t₂) between delays t₁=1.56 ps and t₂=1.72 ps, dominated by electronic dynamics. The added curves are discussed in the text. The polarization of both laser pulses was parallel to the p_z axis. (b) Lineouts of the holographic pattern obtained by integrating the signal inside the grey box in a over p_z, but recorded at the indicated delays that sample one period of the electronic dynamics and are referenced to a delay of 1.05 ps.
