Paper Abstract

We report that the phase of backward Stokes waves can be independently controlled, which is necessary for a beam combination laser using stimulated Brillouin scattering-phase conjugate mirrors (SBS-PCM). 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 Stokes waves via SBS is smaller than λ/4 for all the pump pulses.
