    • The invention relates to a semiconductor laser, which exhibits a flat amplification curve (41) in an energy range around the emission wavelength. When the gradient dgmat/dE (42) of the amplification curve gmat(E) (41) is small (one to two orders of magnitude smaller than in conventional semiconductor materials), the semiconductor laser exhibits a particularly low temperature drift d lambda /dT (43). A flat amplification curve (41) of this type can be achieved by a quantum dot laser (42) with two energy levels, which are separated by a favourable energy band gap and have a favourable amplification ratio in relation to one another. By guiding the process appropriately during the formation of the quantum dot layer, the individual energy levels are spread in such a way that a total amplification curve gmat(E) (41) with a small gradient dgmat/dE (42) is obtained. A temperature-stabilised semiconductor laser of this type can also be achieved by a quantum wire laser.
