Bf.5 Moderne optik og laserfysik (2p)
Introduction to Modern Optics:
In the first semester, the fundamental aspects of classical modern optics are treated. We begin with selected aspects of electrodynamics including the Stokes and Jones vector formalism for polarization and a review of reflection at dielectric and metallic surfaces. Geometrical optics is shown to be a limiting case of wave optics, and selected applications to lens and mirror based systems are presented. Interference and diffraction phenomena are handled with a reasonable degree of rigor.
Coherence theory is introduced and the significance of coherence phenomena in the laboratory are illustrated. The theory of dispersion and the optical properties of materials are briefly reviewed. Finally, the anisotropic properties of materials, which play a key role in laser technology, are discussed in some detail.
Introduction to Laser Physics and Non-Linear Physics:
In the second semester, we introduce the basic concepts of laser physics and nonlinear optics. The interaction of light with matter is first treated on the basis of the time-dependent Schrödinger equation, and rate equations are subsequently developed as an approximation. Laser resonators are discussed both from the viewpoint of an ABCD formalism and diffraction theory.
The basics of laser operations: gain, threshold, power output and frequency are treated with examples based on real systems. Finally, an introduction is given to nonlinear optics. The subtopics include: second and higher-order harmonic generation, parametric couplings, and the stimulated Raman and Brillouin effects.
The two semesters can also be taken as individual courses.
