Recent advances on time-stretch dispersive Fourier transform and its applications

The need to measure high repetition rate ultrafast processes cuts across multiple areas of science. last decade has seen tremendous advances in the development and application new techniques this field, as well many breakthrough achievements analyzing non-repetitive optical phenomena. Several approaches now provide convenient access single-shot waveform characterization, including dispersive Fourier transform (DFT) time-lens techniques, which yield real-time characterization spectral temporal domains, respectively. These complementary have already proven be highly successful gain insight into numerous phenomena emergence extreme events characterizing complexity laser evolution dynamics. However, beyond study these fundamental processes, measurements also been driven by particular applications ranging from spectroscopy velocimetry, while shedding light spanning imaging, metrology or even quantum Here, we review a number landmark results obtained using DFT-based technologies, several recent key selected applications.
