Claim Text:
1. A method comprising: propagating, via a first laser beam, a first laser energy through a first fiber of a multi-core fiber; propagating, via a non-laser energy source a second non-laser energy selected from one of a mechanical energy, sonic energy, and ultrasonic energy within a hollow second fiber of the multi-core fiber; applying the first laser energy to a surface of a substrate to form a liquefied bed on the surface; applying the second non-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 or above the surface of the substrate a three-dimensional anchoring structure upon solidification of the splash of liquefied material.
