Description
This double-clad passive fiber perfectly matches Coractive’s DCF-EY-25/250P-ASEF active fiber. It is ideal for the manufacture of passive components used in the design of high power fiber lasers . Moreover, using this fiber to match the active fiber greatly reduces the splicing loss when building the laser source.
Features & Benefits
- Low background losses
- Excellent geometrical properties
- Compatbile with industry standards
Applications
- Passive component manufacturing
- Laser beam delivery
- Fiber lasers
