Abstract
The two basic approaches underlying the metrology of attosecond pulse trains are compared, i.e. the 2nd order Intensity Volume Autocorrelation and the Resolution of Attosecond Beating by Interference of Two photon Transitions (RABITT). They give rather dissimilar results with respect to the measured pulse durations. It is concluded that RABITT may underestimate the duration due to variations of the driving intensity, but in conjunction with theory, allows an estimation of the relative contributions of two different electron trajectories to the extreme-ultraviolet emission.
