In the EU project “High Performance AlexandriteCrystals and Coatings for High Power Space Applications” (GALACTIC), Laser Zentrum Hannover (LZH) aims to develop a solely European supply chain for space-qualified high-performance laser crystals made of Alexandrite with the partners Optomaterials S.r.l. (Italy) and Altechna Coatings UAB (Lithuania). These laser crystals are to be used in earth observation satellites in space.
