Driven by local field enhancements enhancing feedback, novel structuring features demonstrate the potential of ultrafast laser for the fabrication of self-organized patterns with a periodic topography well below the diffraction limit. We report the achievement of laser-induced nanocavities that results from the control of a Marangoni convection instability at the nanoscale.
