CONTEXT AND GENERAL AIM:
Since their invention in 1960, lasers have become the most important light sources in optics and photonics, and are present everywhere in modern society nowadays. For example, worldwide telecommunication is based on the transmission of laser signals through optical fibers, and today’s manufacturing industry heavily relies on the use of high-irradiance laser beams. Other application domains include medicine, art restoration, remote sensing, biological spectroscopy, and many others. It is the general aim of this course that the students will become able to explain and analyse laser properties and laser-related concepts, that they learn to construct and analyse the mathematical description of important concepts, and that they are also able to apply the latter to practical examples on the use of lasers.
The targeted end competences can be categorized as follows:
spontaneous and stimulated emission, absorption, coherence, heterostructures for efficient light generation, light propagation in a resonator, continuous-wave and pulsed laser action, line broadening, saturation, Gaussian laser beams, operation and applications of different laser types (gas lasers, liquid lasers, solid-state lasers, semiconductor lasers), laser dynamics, noise, Bragg gratings, wavelength tuning, laser packaging.
rate equations describing the general operation principle of laser action and formulas for continuous-wave/pulsed laser operation, formulas for the modes in different types of resonators with different stability criteria, equations for propagation and transformation of Gaussian and multimode laser beams in optical systems, laser rate equations for different types of semiconductor lasers, formulas describing the gain and complex refractive index in semiconductor materials, description of the linewidth of lasers, formulas for the dynamic behaviour of lasers.
The students are evaluated according to the above-enlisted end competences in an oral exam with written preparation (open questions, closed book)
The final grade is composed based on the following categories:
Other Exam determines 100% of the final mark.
Within the Other Exam category, the following assignments need to be completed:
Oral exam with written preparation (open questions, closed book)
The part of the course taught by N. Vermeulen and the part of the course taught by G. Verschaffelt (at VUB) or G. Morthier (at UGent) are examined together.
Partial transfer of the score obtained for an individual part to the 2nd session or the next academic year is not allowed.
