FIELD: technological processes.
SUBSTANCE: invention relates to methods for laser nanostructuring of a surface. Method for nanostructuring the surface of a dielectric substrate according to the invention consists in irradiating a forming system with laser radiation, forming a focused bent electromagnetic beam and irradiating the surface of the substrate with it, wherein the forming system is made in the form of a mesoscale dielectric particle which forms a photonic hook directly on its shadow surface and is placed by its shadow surface on the surface of the dielectric substrate.
EFFECT: invention enables nanostructuring of the surface of a dielectric substrate with formation of a curvilinear crater in the substrate.
