Extended Data Table 3 Amplitudes and harmonic phase differences

From: Attosecond pulse shaping using a seeded free-electron laser

  1. Amplitudes F10, F9, F8 and F7 and phase differences Δφ8,9,10 and Δφ7,8,9 for the three- (Fig. 3) and four-harmonic cases (Fig. 4). For the phase (amplitude) shaping in the three-harmonic case, the photoelectron spectra were rescaled to the area of the peak corresponding to the eighth harmonic in Fig. 3b and e (Fig. 3i and l). For the four-harmonic case, the photoelectron spectra were rescaled to the area of the eighth harmonic in Fig. 4a–c. For the pulse reconstruction, the measured Δφ7,8,9 phases were corrected for the shift of 0.157 rad obtained by the TDSE simulations.
