Dual-wavelength noiselike pulses are generated in a fiber ring laser. A first series of pulses is induced at a wavelength of 1550 nm by the interplay of an erbium-doped fiber and nonlinear polarization rotation. From the Raman gain of these pump pulses emerges a second series of Stokes pulses at 1650 nm. With adequate control of the polarization states in the cavity, the noiselike Stokes pulses extend over 84 nm in the Ultralong-wavelengths band (U-band), while the pump pulses span over 46 nm.
