 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 semiclassical and fully quantum description of interaction between bonded electrons and resonance radiation.
