The students will learn the fundamentals in nonlinear optics and in the dynamics of optically induced processes. They receive an overview about current methods in ultrashort spectroscopy and elementary nonlinear excitations, and its applications in particular cases. The contents include fundamentals of light-matter interactions, wave packet and electron dynamics, experimental methods of ultrafast spectroscopy, as well as selected topics, e.g. femtochemistry, multiphoton excitation, coherent control, and attosecond physics.ausgewählte Anwendungen, z.
