The interaction of laser light with a metal surface yields a complex configuration of point defects, e.g., droplets and holes and vortex microfilaments. When a single filament interacts with a defect it "winds" around the defect and can form loops, and rings. Interaction of a single filament with a single defect gives rise to arc deformation bending, formation of loops and rings, while its interaction with a two-dimensional (2D) random lattice of defects gives rise to the vortex filament splitting and breaking which occur at nodal points of the Voronoi lattice. Interaction of one-dimensional (1D) vortex filament lattice with 2D lattice of defects results in the formation of knotted structures such as the Hopf links as well as 1D and 2D Hopf link crystals, knotted along the sides of the Voronoi lattice. We observed that configurations of vortex filaments are organized at three hierarchical levels of growing complexity. Every level is comprised of the elements of the lower complexity one, indicating the presence of a supercomplexity.
