This subject provides an overview on optical and electrical properties of glasses and ceramic materials based on the classical theory of electromagnetism, i.e. the Maxwell equations, including the Mie theory of scattering, which is the basis for modeling the transmittance of transparent heterogeneous materials and at the same time the key to understanding modern instrumentál applications such as laser diffraction for the characterization of particles. The relation between electrical and optical properties is explained in single crystals, polycrystalline materials and glasses, including electro-optical properties. The presentation takes into account the tensorial and complex character as well as the frequency dependence of the of the respective quantities and also includes nonlinear phenomena and the calculation of effective electrical properties of heterogeneous materials in the long-wavelength approximation. Part of the subject concerns the quantum theory of lasers. Within this subject the student gets acquainted with the preparation of materials with controlled optical and electro-optical properties, with their properties in dependence of the composition and microstructure, including the measurement of these properties, and with challenging modern applications (transparent impact-resistant windows, photonic crystals and metamaterials, solid state lasers and electro-optical devices).
