1. A method comprising:
applying a laser beam to a surface of a solid material to form a liquefied bed on the surface of the solid material;
applying a pulse of laser energy to at least a portion of the liquefied bed to cause a splash of liquefied material outside the liquefied bed; and
forming on the surface of the solid material a three-dimensional anchoring structure upon solidification of the splash of liquefied material;
wherein the applying of the pulse of laser energy to the portion of the liquefied bed is performed subsequent to the applying of the laser beam to the surface of the solid material; and
wherein the applying of the laser beam to the surface of the solid material comprises a scanning by the laser beam over the surface of the solid material.
