Description
Passive components are usually manufactured with a passive fiber that matches the gain fiber as it greatly reduces splicing losses and maximizes transfer efficiency. The DCF-UN-20/125-080 is designed to perfectly match Coractive’s DCF-YB-20/128E and other commercially available active fibers. It is commonly used for manufacturing passive components such as pump combiners and output isolators of high peak power pulsed fiber lasers.
Features & Benefits
- Compatible with industry standards
- Low background losses
- Excellent geometrical properties
Applications
- Passive component manufacturing
- Pulsed fiber laser systems
- Laser marking & engraving
