Open-Loop and Closed-Loop Vortex Filaments Generated in Laser-Matter Interactions

Laser-matter interaction on nanosecond time scale. Generation of a shear layer on metal target. Kelvin-Helmholtz instability and generation of vortex filaments. Ultrafst cooling and conservation of vortex filament structures. Experimental evidence of the open-loop vortex filaments ; Observation of a filament helical pairing ; Observation of vortex filament cascade splitting ; Observation of solitons on filaments ; Observation of a cascade reconnection of vortex filaments. Experimental evidence of the closed-loop vortex filaments. Observation of vortex rings generated in the regime of developed Ťnormalť boiling of metal surface ; First observation of unknotted and knotted tructures of various degree of complexity ; first observation of the Hopf links, trefoil knots... in the real experiment.
