Boxoptronics' Germanium Doped Quad Core Passive Fibers are mainly matched with the four-core erbium-doped fiber, and the high matching reduces the splicing loss and ensures the high- performance output of the multi-core active fiber.
Boxoptronics 2um double-clad passive matching fiber is designed for high-power 2 um pulse or continuous fiber lasers and amplifiers. It has the characteristics of high matching, low fusion loss, high consistency and stability, ensuring the high performance output of thulium-doped fiber in system applications
Boxoptronics' Highly Doped Phosphorus Raman Fibers are designed for efficient Raman lasers and amplifiers operating in the 1.1-1.6 µm spectral range. The main advantage of phosphorous-doped fiber is the three times higher Raman shift value compared to germanium-doped fiber. This feature can greatly simplify the design of Raman fiber lasers and amplifiers.
The Polarization maintaining double clad thulium doped optical fiber is designed for high-power 2 um narrow linewidth fiber amplifiers that are eye-safe. By optimizing Tm ion doping, it has the characteristics of high slope efficiency, high absorption coefficient, and high polarization extinction ratio when pumped at a wavelength of 793nm.
