Ultrafast spectroscopy is an important method to study the light-matter interaction using ultrashort femtosecond laser pulses, which plays an important role in the development of the materials science, chemistry, and physics. In this course, students are expected to learn the fundamentals of ultrafast optics and spectroscopy, related experimental techniques, and the frontiers of the applications with ultrafast spectroscopy. The contents of the course include the fundamentals of light-matter interaction, linear and nonlinear optical effects, the generation and characterization of ultrashort laser pulses, several typical ultrafast spectroscopic methods including ultrafast fluorescence, pump-probe spectroscopy, and two-dimensional spectroscopy, and important applications of ultrafast spectroscopy in materials science, chemistry, and physics. By attending this course, the students will gain basis knowledge of ultrafast spectroscopy, which will be beneficial not only for performing relevant experiments in scientific research but also for working in the field/industry of optoelectronic technology and information, solar energy conversion, and laser instrumentation.
