Ultrashort laser pulse characterization by means of amplitude swing

The advent of ultrafast optics and its several applications has implied the development of a wide range of pulse time domain diagnostics (autocorrelation, FROG, SPIDER, spectral interferometry, d-scan, etc.). Nowadays, the growing application of ultrafast pulses at out-of-lab environments (e.g., industrial) with noise and instability sources is a challenge, requiring a simple and robust measurement technique.
