In this work, we applied an all-optical FROG-CRAB experiment with expansion to characterize the gigawatts IAP duration as a faster reconstruction method. The all-optical FROG-CRAB measurement scheme is using a weak gating pulse (<10-3 in intensity ratio) as a perturb waveform applied to the HHG process with delay changes. The IAP is measured as 224-as duration, which could get a good agreement with the original FROG-CRAB measurement.
