Phosphorus-doped fibers module

Phosphorus-doped fiber module is designed for high efficiency Raman lasers and amplifiers operating in the 1.1-1.5 µm spectral range. The main advantage of this fiber module is a three times higher value of the Raman shift as compared to germanium-doped fibers. This feature greatly simplifies the design of Raman fiber lasers and amplifiers design by reducing the number of Raman wavelength conversion cascades. Greitlex offers the highest Raman gain Phosphorus-doped fiber module on the market.
