Course outline

Course content

• Black body. Planck, Rayleigh-Jeans, Wien, Stefan-Boltzmann laws.
• Electromagnetic (EM) waves: Boundary conditions, normal modes in a cavity.
• Discrete spectrum. Two-level system (2LS) or multi-level system (mLS): Atom, quantum dot, color center. Stmulated – spontaneous absorption and emission processes.
• EM radiation - 2LS or mLS interaction, semi-classically. Dipole approximation. Time-dependent perturbation theory. Rabi frequency. Rotating wave approximation. Allowed transitions.
• EM radiation - 2LS or mLS interaction, quantum mechanically. EM field quantization. Spinors. Commutators. Anticommutators. Transition dipole moment. Photon absorption-emissionDensity matrix.
• LASER: Pumping, population inversion, rate equations, longitudinal and transverse EM modes, LASER types.
