TLDR
In this paper, the authors cover the principle of dispersive Fourier transformation and its implementation in diverse applications, such as optical rogue waves and rare cancer cells in blood, as well as their application in real-time instrumentation and measurement.Abstract:
It's challenging to measure non-repetitive events in real time in the field of instrumentation and measurement. Dispersive Fourier transformation is an emerging method that permits capture of rare events, such as optical rogue waves and rare cancer cells in blood. This Review article covers the principle of dispersive Fourier transformation and its implementation in diverse applications.read more

Real-Time Observation of the Buildup of Soliton Molecules.
TL;DR: The first observation, to the best of the knowledge, of the entire buildup process of soliton molecules (SMs) in a mode-locked laser is reported and the evolution of pulses in the raised RO stage follows a law that only the strongest one can ultimately survive.

Introduction to Spectroscopy
TL;DR: In this paper, the authors present an overview of the basic concepts of one-dimensional NMR, including spin spin-spin coupling, spin-spin coupling, Heteronuclear coupling with other nuclei, and 13C coupling constants.
Journal ArticleDOI
Optical rogue waves
TL;DR: This work reports the observation of rogue waves in an optical system, based on a microstructured optical fibre, near the threshold of soliton-fission supercontinuum generation—a noise-sensitive nonlinear process in which extremely broadband radiation is generated from a narrowband input.
