The Laser

  • Hermann Haken
  • Hans Christoph Wolf


The laser has become a light source without which modern spectroscopy could not exist (see also Chap. 22). In addition, the processes which lead to emission of laser light are a beautiful example of the application of basic knowledge about interactions between light and atoms. For both reasons we shall treat the laser in detail here.
