Complete pulse characterization based on temporal interferometry using an unbalanced temporal pulse shaping system

In this paper, we demonstrate a simple method for the full characterization of an ultrashort optical pulse based on temporal interferometry using an unbalanced temporal pulse shaping (UB-TPS) system. The UB-TPS system is functioning to generate and stretch two time-delayed replicas of the input pulse. The magnitude and phase information of the input pulse is reconstructed from the recorded temporal interference of the two time-delayed and dispersed pulses based on a Fourier transform algorithm.
