The course "Nonlinear Photonics" covers the modern theoretical and experimental foundations of nonlinear optical phenomena. The course covers the generation of ultrashort optical pulses, their characterization, as well as their propagation in an optical medium. During the course, students will study the basic mechanisms of nonlinear interactions of light with matter, such as self-focusing, harmonic generation, solitons, and supercontinuum generation. Special attention is paid to the application of nonlinear processes in science and industry. The course includes lectures, as well as practical seminars as a meeting of journal clubs for in-depth discussion and analysis.
