Abstract

Future space missions require more efficient coatings with high stability over time. The Far-UV (FUV) (100-200 nm) and Extreme-UV (EUV) (10-100 nm) spectral ranges are of great interest to various scientific communities dedicated to the exploration and understanding of the universe. GOLD laboratory is a scientific research group that investigates on the development of coatings tuned in the FUV and EUV spectral ranges. In this proceeding, we present coatings that address different targets: 1) broadband mirrors based on Al/MgF₂ and Al/AlF₃, 2) narrowband mirrors peaked at wavelengths longer than ~120 nm based on (MgF₂/LaF₃)_n multilayers, and 3) mirrors with high reflectance at Lyman β (102.6 nm) spectral line with strong rejection at the ubiquitous and intense H Lyman α(121.6 nm).
