Ultrashort laser pulse retrieval using single-shot VAMPIRE

Characterizing ultrashort laser pulses is a challenging task. By now several methods are established which can be divided into interferometric methods like SPIDER (spectral phase interferometry for direct electric field reconstruction) [1] or MEFISTO (measurement of the electric field by interferometric spectral trace observation) [2] and spectrographic methods like FROG (frequency-resolved optical gating) [3] or TASC (temporal analysis of spectral components) [4].
