Abstract
We shows that the phase of a backward stimulated Brillouin scattering (SBS) wave can be controlled, which is necessary for a beam combination laser using SBS phase conjugate mirrors. The phase control is achieved by a self-generated density modulation without seeding the Stokes beam. Theoretical analysis shows that the phase fluctuation is mainly due to the pump energy fluctuation and is inversely proportional to the pump energy. We have achieved that the relative phase difference between two SBS waves is smaller than λ/4 for all the pump pulses.
