In a bulk Kerr material, no analytical solution is known to yield stable soliton beam propagation. The most frequent experimental situation leads to a well-known chaotic beam break-up into numerous randomly distributed self-focused spots. An interferometric method is proposed to achieve a 1D phase-matching of the self-focused spots through a Kerr-induced index grating. By this way, self-splitting of the laser beam into multiple solitons occurs in bulk CS2. When the material exhibits stimulated scattering in the picosecond or nanosecond range, the present method yields also to a distributed feedback that gives rise to Raman or Brillouin soliton-like beams.
