Comparison of RABITT and FROG measurements in the temporal characterization of attosecond pulse trains
arXiv:0707.4228
Abstract
The attosecond high harmonic pulses obtained from a long Ar-filled gas cell were characterized by two techniques - the reconstruction of attosecond beating by interference of two-photon transition (RABITT) and frequency-resolved optical gating (FROG) methods. The pulse durations obtained by RABITT and FROG methods agreed within 10 %.
