In this WP the LIBS Laser system and spectrometer unit fabrication and verification are conducted along with the manufacturing of all LIBS hardware. Moreover, the manufacturing of the pressure housing which will accommodate the LIBS system was carried out based on the assessments and the design guidelines derived from WP2. Two types of tests are taking place, the first one being the preliminary test of the LIBS system and the pressure housing itself on a pressure chamber and secondly, the overall system integration and functionality test in real life deep-water conditions.
