The students understand the principle of lasers and how coherent light is generated. Second, they have learned how these principles are used in different laser sources and how existing lasers are designed. Finally, they have accumulated knowledge of optical components to control and manipulate laser light e.g. to convert wavelengths and to generate short and ultrashort laser pulses.
After an introduction into the different energy levels in atoms and molecules and a basic description of the quantum mechanics concept the different principles of light-matter interaction are derived, i.e. absorption, spontaneous emission and stimulated emission. Second, the rate equations will be presented and effective amplification of light will be discussed. In the following, resonator concepts will be investigated and a complete description of the laser becomes possible. In the next chapter optical components, polarisation and birefringence are explained and methods to generate short and ultrashort pulses. Based on this knowledge the different laser sources will be presented subdivided into solid-state lasers, gas lasers, liquid dye lasers and semiconductor lasers. Finally, non-linear optics is explained in order to generate new wavelengths.
