Abstract
Within the framework of the Virgo project, characterisations of low-absorption high reflectivity multilayers coatings by collinear mirage effect at 1064µm are reported. All the tested samples have absorption losses lower than 20 ppm and the lowest observed average absorption loss is 0.99 ppm.
