Stimulated Brillouin scattering (SBS) is used for multiple-beam combining by overlapping the beams in the SBS interaction volume and for phase control by backseeding the interaction volume. Tripled Nd:YAG laser experiments and wave-optics analyses indicate the conditions of beam overlap, power, and focusing that are required to obtain effective beam combining and phase control.
