Details Introduction
Product DescripⅥon
The 400 μm cladding diameter double cladding Yb-doped fiber is composed of an opmized fiber preparaon process and high-performance glass. Designed for connuous lasers in the 3 kW class and above, the fiber features near-single-mode transmission, low bending loss, low photon dark- ening, and high efficiency, and it can be widely used in materials processing, medicine, and scien- fic research.
Features
• Highly accurate geometric dimension control
• Near single-mode transmission
• High laser slope efficiency
• High mode instability threshold
• Low photon darkening effect
• Reliable stability in high temperature and high humidity environments
• Both PM and non PM are customized
• Radiaon resistant types are available
ApplicaⅥons
• Industry and scienfic research
• High power connuous fiber lasers and amplifiers
