We present the first experimental demonstration of a resolvable mode structure with spacing in the RF spectra of ultralong Raman fiber lasers. The longest ever demonstrated laser cavity , RF peaks of width and spacing have been observed at low intracavity powers. The width of the peaks increases linearly with growing intracavity power and is almost independent of fiber length.
