This work discusses the results of research into comparative efficiency of non-linear transformation of picosecond single- and double-scale fibre laser pulses in generation of Raman-dominated supercontinuum (SC) due to cascaded stimulated Raman scattering of these pulses in a long extra-cavity fibre. We demonstrate properties of SC formed by superposition of spectra of several Stokes components when pumped with pulses of different structure. More efficient Raman transformation of double-scale pulses was identified, leading to broader SC spectra. The work presents features of temporal distributions of radiation intensity of single- and double-scale pulses-induced SC at different average input powers.
