This is the website for the EU funded H2020 research and innovation project GALACTIC. The goal of this project is to set up the European supply chain for space-qualified Alexandrite laser crystals.
The European Union wants to use the unique properties of Alexandrite crystals in Earth observation satellites in the future. To make the EU independent of non-European suppliers, the Laser Zentrum Hannover e.V. (LZH), Altechna Coatings,…
At the SPIE Laser Damage 2021 (12-15 October), Laurynas Lukoševičius of Altechna Coatings (LT) shall be presenting his latest work on Alexandrite laser crystal pretreatment. Watch his poster presentation on the ‘Development of alexandrite laser…
High-power applications in space place high demands on Alexandrite laser crystals. Therefore, they must be pretreated before coating to achieve the highest damage thresholds and lowest optical losses. At the SPIE Optical Systems Design Digital…
Complementing the poster presentation at the virtual International Conference on Space Optics (30 March – 02 April 2021), GALACTIC has now published the proceedings paper on “High performance Alexandrite crystals and coatings for high power…
The ICSO (30 March to 2 April 2021) is a bi-annual forum for technology and mission experts. Fostering the exchange about optical technologies for space missions, the virtual event is the perfect platform for presenting…
