Fig. 3: SH-FROG measurements.

From: Near-zero-index ultra-fast pulse characterization

Fig. 3

a SH FROG traces experimentally acquired from our AZO film. b Reconstructed FROG traces generated by the FROG retrieval algorithm (Retrieval error of 0.0027). c Recovered temporal amplitude (solid blue line) and phase (dashed orange line) profiles (FWHM time duration \(\triangle t=30.61{fs}\)). d Recovered spectral amplitude (solid blue line) and phase (dashed orange line) profiles. This plot also reports the experimentally acquired input spectra (dotted green line) for comparison.
