Learning Outcomes
Upon successful completion of the course the students will be able to understand, in not a detailed mathematical description, the nature of electromagnetic radiation, fundamental principles of interaction between radiation and matter, statistical properties of photons and sources, the basic LASER operating principles, the physics of underlying phenomena, the ways of their implementation and as well as the various types of LASER based on the above operating principles. Finally, the students will acquire solid knowledge about possible applications areas of a LASER, depending on its type and properties.
