Shanghai Gengyun Industrial Co., Ltd
TOEM offers a variety of thulium-doped active fiber s suitable for high, medium and low power applications.
The thulium-doped active fiber feature a unique design with a low numerical aperture core and high concentration thullum doping. The operating wavelength of the Tm-doped fibers is around 2.0μm, within the eye-sale wavelength range. They are applicable in fields such as LiDAR, laser medicine, and special material processing etc. The fiber is fully optimized for slope efficiency when pumped at 793nm. The high concentration Tm doping enables users to achieve higher pump conversion efficiency with shorter fibers. The low numerical sporture core design ensures single-modelaser transmission within the core.
