title: Cascaded SRS of single- and double-scale fiber laser pulses in long extra-cavity fiber.
abstract: This work presents, for the first time, the results of studies of stimulated Raman scattering (SRS) in 1.2-km P2O5-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.
