High-frequency periodic patterns driven by non-radiative fields coupled with Marangoni convection instabilities on laser-excited metal surfaces
The capability to organize matter in spontaneous periodic patterns under the action of light is
critical in achieving laser structuring on sub-wavelength scales. Here, the phenomenon of …
