After an introduction into atomic energy levels and a basic description of the quantum mechanics
concept the different principles of light-matter interaction
(i.e. absorption, spontaneous emission and
stimulated emission) are explained. 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. Based on this knowledge the
different laser sources will be presented subdivided into
solid-state lasers, gas lasers, liquid dye lasers and
semiconductor lasers.
