We propose and experimentally realize a composite Raman converter based on P-doped and Gedoped fibers. The converter has an emission wavelength of 1.649 μm and an output power of 1.2 W. Numerical simulation of the configuration suggested was performed. A similar converter scheme can be used to build sources with any emission wavelength in the range from 1.6 to 1.75 μm.
