Shanghai Gengyun Industrial Co., Ltd
T-AOF53307,TOEM offers a variety of ruthenium-doped active optical fibers to meet high, medium, and low power applications. These fibers feature a unique low numerical aperture core and high ruthenium ion doping concentration. Operating at approximately 2.0 μm, within the eye-safe wavelength range, they are suitable for applications such as lidar, laser medicine, and the processing of special materials. The iron-doped active fiber optimizes the slope efficiency at 793 nm pumping. The high ruthenium ion doping concentration allows users to achieve higher pump conversion efficiency with shorter fibers. The low numerical aperture core design ensures single-mode laser transmission within the fiber. TOEM can also provide customized product services to meet specific customer needs.
