Stimulated Brillouin scattering (SBS) and Kerr-nonlinear four wave-mixing\n(FWM) are among the most important and widely studied nonlinear effects in\noptical fibres. At high powers SBS can be cascaded producing multiple Stokes\nwaves spaced by the Brillouin frequency shift. Here, we investigate the complex\nnonlinear interaction of the cascade of Stokes waves, generated in a\nFabry-Perot chalcogenide fibre resonator through the combined action of SBS and\nFWM. We demonstrate the existence of parameter regimes, in which pump and\nStokes waves attain a phase-locked steady state. Real-time measurements of 40ps\npulses with 8GHz repetition rate are presented, confirming short-and long-term\nstability. Numerical simulations qualitatively agree with experiments and show\nthe significance of FWM in phase-locking of pump and Stokes waves. Our findings\ncan be applied for the design of novel picosecond pulse sources with GHz\nrepetition rate for optical communication systems.\n
