Ultrafast spectroscopy is a powerful tool to study the various dynamics of materials, electronic and optoelectronic devices, chemical reaction and biology processes. The capability of ultrafast spectroscopy has been greatly extended in various directions in terms of time resolution (attosecond), spatial resolution (near field with subwavelength), and wavelength range (far IR and deep UV and X-ray). Rapid progress in ultrafast spectroscopy relies on two cornerstones in this field — powerful emerging spectroscopy methods and ultrafast light sources that can emit short pulses. The 1st Germany-China young scientist symposium for ultrafast light sources and spectroscopy applications will bridge the gap between the light source developers and the users. The symposium will bring together leading young scientists from Germany and China, who are working on ultrafast light sources and ultrafast spectroscopy, to present their recent research progress, aiming to brainstorm new ideas, identify novel research directions, and foster future research collaboration.
