Details Introduction

Double-cladding Ytterbium Doped Fiber is an active optical fiber used in 1μm fiber lasers. Lasers made with the fiber cavity can be widely used in material processing, medical care, and scientific research. Fiber lasers are widely used for their lightweight, high e_x001D_ciency, and stability compared with traditional solid-state lasers.

Applications

• Industry/ Medical

• CW / Pulse fiber laser

• High peak-power / High

• average-power fiber laser

Characteristics

• The large preform process guarantees precise geometric control and batch stability

• High ytterbium-doped concentration

• High laser slope e_x001D_ciency

• Low photo-darkening

• High reliability coating
