All-fiber Raman supercontinuum generator

The results on an all-fiber supercontinuum generator that exhibits a continuous wide spectrum in the range 1060–1640 nm predominantly owing to the cascade stimulated Raman scattering in a single-mode quartz fiber at a relatively high power of the combined femtosecond-picosecond pumping with a central wavelength of 1080 nm are presented for the first time. The mean power of the supercontinuum is 2.1 W.
