The threshold power of a Stokes line of order higher than 3 has appeared sooner than the saturation power of the last Stokes line due to degenerate FWM processes involved in the MBRFL generation. It is interesting to note that the nth order anti-Stokes and (n+4)th order Stokes power levels increased unexpectedly almost the same before the Stokes wave reached at its threshold power.
