Students will acquire knowledge in nonlinear optics and deepen their understanding of general optics, laser physics, and ultrashort pulses. They will deepen the understanding of light-matter interaction in classical as well as quantum mechanical frames, which can be a basis for further studies, e.g., in ultrafast physics, attosecond physics, linear and nonlinear spectroscopy, nonlinear microscopy techniques, and many more. They will get to know many specific applications, such as frequency doubling, frequency conversion processes, supercontinuum generation in nonlinear fibers, stimulated Raman scattering, ultrafast switching or ultrafast electron microscopy. The lecture will prepare for a master thesis bearing connection to optics.
