1. A method for labeling a material, the method comprising:

  • focusing a first high energy electromagnetic or particle wave generator, producing a wave transmissible to a subsurface of a material without causing any substantial disruption of the surface of the material, on a first portion of said subsurface;

    focusing one or more second high energy electromagnetic or particle wave generator(s), producing a wave transmissible to a subsurface of said material without causing any substantial disruption of the surface of said material, on said first portion of said subsurface;

    wherein the first and second generators are set in combination to allow for marking said first portion of said subsurface without any substantial disruption of the surface of said material, but the setting individually of which alone does not allow for said marking of said first portion of said substrate.
