This double-clad passive fiber perfectly matches Coractive’s DCF-YB-30/250EH active fiber. It is ideal for the manufacture of passive components used in the design of high peak power pulsed fiber lasers for material processing applications. Moreover, using this fiber to match the active fiber greatly reduces the splicing loss when building the laser source.
