Abstract :
We have shown that the phase fluctuations of the phase-controlled stimulated Brillouin scattering (SBS) beams for the beam combination are induced by the various causes, and some of them such as the convective flow can be suppressed. In addition, we have shown that the longer pulse more than the acoustic decay time induces the phase fluctuation due to the phase jumps.
