This work presents, for the first time, the results of studies of stimulated Raman scattering (SRS) in 1.2-km P 2 O 5 -doped silica fiber of radiation of single-and double-scale picosecond pulses generated in a fiber master oscillator and amplified in a one-stage fiber amplifier. Shown are differences in supercontinuum spectra composed of several Stokes components when pumped with pulses of different structure. More efficient Raman transformation of double-scale pulses was identified, leading to broader supercontinuum spectra.
