Thulium-doped Fiber
Everfoton Double-cladding Thulium-doped Fiber is an active gain fiber used for 2 μm fiber lasers and amplifiers. This series of fibers achieves high slope efficiency and low nonlinear effects when pumped at 793 nm by optimizing the profile and thulium ion doping concentration design. It can be widely used in the fields of medicine, material processing, and opto-electronic countermeasures.
