The CJ high-phosphorus-doped Raman fiber is specifically designed for efficient Raman lasers and amplifiers operating in the 1.1–1.6 μm spectral range. Compared with germanium-doped fibers, the main advantage of phosphorus-doped fibers is a Raman shift value three times higher. This characteristic can significantly simplify the design of Raman fiber lasers and amplifiers.
