Smart Product Number: PLMA-YDF-30/400-VIII
30/400 Ytterbium-Doped LMA Double Clad PM Fiber
Nufern's 30/400 Ytterbium-doped double clad fiber is designed to combine the features of large 30 µm core diameter for generating high pulse energy together with a large 400 µm cladding optimized for high average powers, while still delivering good beam quality through the adoption of LMA fiber design. Available with latest generation of glass technology, the Gen. VIII 30/400-YDF fiber is available in two versions-standard and PANDA-stye PM.
