Course: Laser Physics

Department/Abbreviation: OPT/IZL

Year: 2021

Guarantee: 'prof. Mgr. Radim Filip, Ph.D.'

Annotation: The goal of course is to introduce basic physical principles of laser and micromaser, their semi-classicial and quantum dynamics and quantum statistics of radiation.

Course review:
1. Road to laser and maser. Motivation for a discovery of laser and maser. 2. Principles of oscillators with a feedback. Interaction of light in a classical dielectric medial. 3. Einstein quantum theory, amplification of light by stimulated emission, population inversion. 4. Three-level and four-level laser, thermal and pulsed pumping, types of lasers. 5. Nonlinear evolution of laser intensity, threshold for lasing, saturation of light in laser. 6. Stability of laser intensity, transient effects, mode cooperation and competition. 7. Photon statistics of laser, laser noise, Poissonian statistics and photon statistics measurement. 8. Quantum state of laser light versus thermal radiation, detection of quantum states of laser and their application. 9. Quantum model of atom-light interaction, atomic coherence, micromaser.
