Results of laboratory experiments on control of the filamentation domain of a focused femtosecond laser beam with a spatially structured (with a deformable mirror) wavefront are described. Aberration beams consisting of coherent interleaved ring subapertures obtained with a deformable mirror of specific form are studied. This allows producing inhomogeneities in the distribution of the optical field amplitude during laser beam propagation; these inhomogeneities can subsequently become seeds for light filaments. This approach to control high-power radiation filamentation does not require compensation for distortions of the initial beam profile; on the contrary, it is based on a controllable introduction of pre-calculated wavefront aberrations.
