This course will introduce students to a wide range of optical spectroscopic techniques used to investigate dynamics in matter occuring on extremely short time scales, from picoseconds to attoseconds
Læringsmål:
En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:
explain the key features of ultrashort laser pulses related to ultrafast spectroscopy, such as pulse duration, dispersion, bandwidth, and intensity
explain each of the optical techniques and be able to analyze simulated data sets to extract dynamic physical quantities
relate the different optical techniques and the information obtained to one another in explaining a particular ultrafast physical phenomenon
analyze a given problem, and devise suitable ultrafast spectroscopic techniques to obtain relevant information on the relevant ultrafast process.
Kursusindhold:
Over a 13 week periode we will introduce you to 10 different optical techniques to study ultrafast phenomena.
The course will cover: - Introduction to ultrafast phenomena and review of ultrafast lasers - Transient absorption/reflection spectroscopy - Four-wave mixing spectroscopy - Femtosecond 2D-IR spectroscopy - Time-resolved photoluminescence - THz emission spectroscopy - Time-resolved THz spectroscopy - Femto-acoustic spectroscopy - Magneto-optical Kerr effect - Ultrafast electron diffraction - Attosecond science
We will explain the operating principles behind each technique, show what information can be obtained in relation to physical phenomena, and give particular scientific examples by reviewing classic papers from the literature.
This course will serve as an excellent introduction to ultrafast science and will provide students with an excellent basis for exploring the world of ultrafast science.
