Aim

The course aims at providing knowledge about the physical principles of lasers as well as to give an orientation of the different laser types and laser techniques.

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• know how a laser works.
• understand important concepts such as stimulated absorption and emission, homogeneous and inhomogeneous broadening, diffraction, electromagnetic propagation in a cavity, dispersion, amplification, mode-locking.
• be able to orient himself / herself among the different lasers for a given application.

Competences and Skills

For a passing grade the doctoral student must

• independently be able to perform alignments and measurements on different lasers.
• be able to calculate conditions for lasing and amplification as well as propagation of a laser beam through optical components.
• be able to solve problems in Optics and Lasers.
• be able to acquire, integrate and evaluate knowledge and facts from literature in English within the field.
• be able to present the results of a project in writing
• have an increased experience for working in groups of two or four persons towards a common goal.
