Abstract :
Generation of high-repetition-rate modulation instability pulse trains and high- energy soliton-Raman pulses of ≃60 fs durations, in a single-mode P2O5-doped silica fiber, is reported. The 7 mol.% concentration P2O5 fiber was pumped in a single pass arrangement by a Q-switched and mode-locked Nd:YAG laser operated at 1.319 μm. Operating in the region of zero second-order dispersion, modulation instability Stokes sideband seeded resonantly cascade stimulated Raman scattering associated with Si-O-Si and P=0 vibration modes of the fiber. As a result, broad bandwidth and widely tunable 1.36-1.80 μm femtosecond pulses were obtained
