Course Enrolment Limitations

The course is offered to students of any study field.

Course objectives

The aim of the subject is to introduce optical spectroscopy with the outlook of its application for optical diagnostics of plasma. There are two sub-aims: 1. To provide to students the basics of atomic and molecular physics, which are needed for explanation of optical emission spectra of atoms and molecules (e.g. interactions in atom and their impact on the spectra, term and state notation, effect of external fields...) 2. To provide to students the possibility to try the basic spectroscopy measurement on exceptional laboratory equipment.

Learning outcomes

At the end of the course the students will understand basics of atomic and molecular physics making possible to use them for diagnostics of plasmas by means of optical spectroscopy. Students obtain practical experiences at laboratory measurements of typical spectra as well as at solutions of typical problems from atomic and molecular spectroscopy.
