Dynamics of a multi-wavelength Brillouin-Raman fiber laser (MBRFL) assisted by four-wave mixing has been investigated through the development of Stokes and anti-Stokes lines under different combinations of Brillouin and Raman pump power levels and different Raman pumping schemes in a ring cavity. 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.
