P-doped fiber \v]}
FORC-RAS’s P-doped fiber is specially designed for highly efficient Raman lasers and amplifiers operating in the 1.1-1.6 μm spectral range. 8, YF>O&
The main advantage of phosphorus-doped fiber is a three times higher value of the Raman shift as compared to germanium-doped fibers. This feature allows one to strongly simplify the Raman fiber laser and amplifier design. y?<[g;MuT
For example, to construct a high-power laser @ 1480nm required for pumping Er-doped fibers, only two cascades of Raman wavelength transformation are necessary, whereas six cascades are necessary in the case of Ge-doped fibers. (p`'Okw
