Raybium is a spin-off company with the core business of developing high performance optical fibres for fibre lasers. Fibre lasers are widely used in several industrial applications such as cutting, welding and marking of steel, foil and plastics. Raybium is a supplier of rare-earth (RE) doped fibers for fiber laser applications. The core competence is development of high performance RE-doped silica fibers for e.g. OEM integration. Raybium offers a new type of ytterbium doped silica fibers meeting high demands on efficiency and reliability (high photodarkening resistance). The fibers are available in several standard dimensions including both PM- and non-PM versions. Raybium also provide other RE-doped fibers on request (erbium, thulium).
