KurzbeschreibungBecause of their aesthetic nature crystals are termed "flowers of mineral kingdom". The aesthetic aspect is closely related to the symmetry of the crystals which in turn determines their optical properties. It is the purpose of this course to stimulate the understanding of these relations with a particular focus on those phenomena occurring in intense light fields as they are provided by lasers.
LernzielIn this course students will at first acquire a systematic knowledge of classical crystal-optical phenomena and the experimental and theoretical tools to describe them. This will be the basis for the core part of the lecture in which they will learn how to characterize ferroelectric, (anti)ferromagnetic and other forms of ferroic order and their interaction by nonlinear optical techniques.

InhaltCrystal classes and their symmetry; basic group theory; optical properties in the absence and presence of external forces; focus on magnetooptical phenomena; density-matrix formalism of light-matter interaction; microscopy of linear and nonlinear optical susceptibilities; second harmonic generation (SHG); characterization of ferroic order by SHG; outlook towards other nonlinear optical effects: devices, ultrafast processes, etc.
SkriptExtensive material will be provided throughout the lecture.
