title: Misalignment sensitivity of beam combining by stimulated Brillouin scattering.
abstract: Stimulated Brillouin scattering beam combining is shown to be extremely sensitive to optical misalignments. For the coupling of two overlapping beams, the angular misalignment bandwidth is of the order of 1 mrad, which corresponds to a separation of +/-0.64 beam spot diameter. This occurs for beam displacements normal to the plane defined by the beams' propagation paths.
