The main goal of this course is to make students acquainted with X-ray lasers and their optics. During the last
decade, the X-ray lasers passed through an extensive development. Due to their unique properties (extremely
short wavelengths < 30 nm; ultra-high peak intensitites), the X-ray lasers represent important scientific tools in
various fields of research, e.g. material research, warm dense matter, biophysics, and diffraction imaging.
Principles of X-ray lasers, X-ray optics, and applications are the main subjects of this course.

The oral exam consists of two parts. The first part is devoted to derivations of fundamental physical formulas related to X-ray sources and optics. The second part is dedicated to a general discussion about a selected topic. The exam takes approximately 60 minutes including 30 minutes for preparation. Last update: Chalupský Jaromír, Mgr.
