Course Objective

The main objective of this course is to provide students with the skills to evaluate the interaction between Electromagnetic Waves (EMW) and materials and production as well as manipulation, organization and use of EMWs. Students will gain the ability to produce sustainable solutions in their future professional careers how to manage EMW for several/different purposes such as materials processings, productions, analysis as well as developinf EMW based technologies.

Learning Outcomes of the Course Unit

1   Explain the physical principles of laser operation, including spontaneous and stimulated emission, absorption, and population inversion.
2   Identify and compare various types of lasers, and describe their emission characteristics such as coherence, monochromaticity, and directionality.
3   Analyze the interaction of electromagnetic radiation with atoms, ions, and semiconductors, using both semiclassical and quantum electrodynamics approaches.
4   Describe broadening mechanisms and decay processes that influence the emission and absorption spectra in optical media.
5   Interpret the propagation of laser beams through optical systems, including Gaussian beam behavior, dielectric interfaces, and interferometric setups.
