In this letter, we propose a novel frequency model to evaluate the pump-to-signal relative intensity noise (RIN) transfer in stimulated Brillouin scattering (SBS). For the first time, the RIN transfer in Brillouin fiber amplifiers has been numerically determined in the pump depletion regime both in the time and frequency domains. Moreover, an analytical expression of RIN transfer has been derived from the well-known SBS coupling equations when pump depletion is ignored. Experimental results are found to be in good agreement with the theoretical analysis.
