The instant invention relates to a laser system for optical free space communications, in particular the generation of amplified laser light under conditions in outer space. In the process, an optical beam (72) to be amplified is conducted via a polarizing beam splitter (71) to a Faraday rotator (70) and brought from there to a neodymium crystal (68). By means of reflection, appropriate diffraction and passage through a quarter-wave plate (67), a multiple passage through the neodymium crystal (68) is forced and amplification is achieved by this. |
