GALACTIC Project Develops Alexandrite Laser Crystals for Space
HANOVER, Germany, May 10, 2023 — Under the European Horizon 2020 project GALACTIC, partners Laser Zentrum Hannover (LZH, Germany), Optomaterials (Italy), and Altechna (Lithuania) have established a European supply chain to produce alexandrite laser crystals used in space applications. The alexandrite crystals from the GALACTIC project were grown by Optomaterials and coated by Altechna to withstand the harsh conditions in space. Courtesy of LZH. Alexandrite crystals have robust thermal conductivity and fracture strength,
