Department of Laser Physics and Photonics

Synopsis:

The course is focused to the description of quantum generator behaviour using the general principles of quantum statistical physics. The aim of the lecture is to introduce the theoretical basis of laser generator function using semi-classical and fully quantum description of interaction between bonded electrons and resonance radiation.
