The course starts with a semi-classical description of light-matter interaction, and establishes Maxwell-Bloch equations. The rate equation approximation is used to provide operational principles of the single frequency laser. Starting from this description, transition broadening mechanisms, dynamical regimes, and noise properties of lasers are described. The spatial aspects are then examined, using paraxial transfer matrices to describe cavity stability and beam propagation. Finally, ultrafast lasers using mode-locking are studied along with related subjects such as the propagation and characterization of femtosecond pulses and attosecond pulses generation.
