The initiative created a complete and independent European supply chain for the production of space-qualified alexandrite laser crystals, eliminating dependence on non-European suppliers.<\/b><\/span><\/h3><p><b>Purpose:<\/b> To develop and qualify highly-doped alexandrite crystals with functional coatings for laser systems intended for Earth observation missions from space, such as atmospheric LIDAR. The objective was to increase the technology readiness level (TRL) of European crystals from TRL 4 to TRL 6 through rigorous environmental testing.<\/p><p><strong>Expected results:<\/strong> Optimization of crystal growth processes to achieve doping concentrations above 0.22 at% Cr; development of optical coatings with high laser-induced damage threshold (LIDT &gt;15 J\/cm\u00b2); demonstration of laser performance in representative configurations; environmental qualification through thermal cycling and irradiation.<\/p><p><strong>Results achieved:<\/strong> Production of crystals with doping up to 0.262 at% Cr; development of AR and HR+HT coatings with LIDT up to 28 J\/cm\u00b2 in raster scan mode; laser demonstration with 2.8 ns pulses and energy of 514 \u03bcJ at 5 kHz (system 2) and 98 ns pulses with energy of 3 mJ at 100 Hz (system 1); successful completion of TRL 6 environmental tests without significant degradation; performance superior to or comparable with international competitors.<\/p><p><span style=\"color: #04349b;\"><strong>PROJECT CODE:<\/strong><\/span> Ricerca_1C-115 Cod.118-17\u00a0<\/p><p><span style=\"color: #04349b;\"><strong>PROJECT TITLE:<\/strong><\/span> Alex4Space\u00a0<\/p><p><span style=\"color: #04349b;\"><strong>CUP:<\/strong><\/span> G18C18000010006\u00a0<\/p><p><span style=\"color: #04349b;\"><strong>PERIOD:<\/strong><\/span> 18\/09\/2017 &#8211;
