Abstract
AbstractAfter several decades of dedicated laser development for astronomical adaptive optics, this is the first time that high output power is combined with an optimized laser format, maximizing the coupling of the laser light to the sodium atoms in the Earth's atmosphere. By re‐emission of the absorbed light, an artificial star is created that is used to measure atmospheric distortions and correct astronomical images faster and more reliably than ever before. The effort of the collaboration between the European Southern Observatory (ESO), Toptica Photonics, and MPB Communications has been recognized recently with the third prize of the Berthold Leibinger Innovation Award.
