285120 Ultrafast Science: Lasers, Fundamentals and Spectroscopy (V) (SoSe 2020)

This course is designed to prepare the students for a successful experimental BSc, MSc or PhD project in the area of modern ultrafast condensed matter physics and ultrafast photonics. This course will consist of two parts: the core lecture and a series of guest lectures.

The core lecture will cover the following topics:

- Principles of lasers

- Generation, characterization and propagation of ultrashort laser pulses

- Basics of nonlinear optics and nonlinear wave conversion

- Refresher on sold state physics: electronic bandstructure, phonons, density of states

- Principles of light-matter interaction: dielectric function and its equivalents (optical conductivity, refractive index and absorption coefficient) from classical and quantum mechanical principles

- Examples of ultrafast spectroscopy: time-resolved terahertz (THz) and attosecond spectroscopy

Parallel to the core lecture, a number of guest lectures by leading international scientists will be given, covering such topics as:

- Nonlinear terahertz (THz) science
- Free-electron lasers
- Quantum-cascade lasers
- Nearfield THz spectroscopy and scanning tunneling microscopy
- Nonlinear THz spectroscopy of crystal lattice
- Surface sensitive second order spectroscopies
- Attosecond science

Oral examinations will be held on request.
