Abstract

We report on research into the properties of supercontinuum (SC) generated from low-coherence bursts of different duration in a 1-km long P2O5 fibre. It was found out that SC with a spectral width of ∼135-150 nm is formed within the ∼900-1200-nm range mostly due to cascaded Raman scattering of noise-like pulses with the variable envelope duration of 36-153 ps (sub-pulse duration was ∼ 300 fs) and average power of 560 mW at 1080 nm. It was discovered that the spectral width of SC is predominantly affected by the duration of interaction between the pumping and Raman pulses.
