1. A method for selectively ablating one or more layers of a layered material, the method comprising:

  • (a) selectively adjusting ultrafast laser output of an ultrafast laser device based upon one or more physical attributes of a layer of the layered material;

    (b) applying the ultrafast laser output of the ultrafast laser device to the layer of the layered material along a tool path to ablate the layer along the tool path;

    (c) re-executing steps (a) and (b) to ablate one or more additional layers, the re-execution of steps (a) and (b) occurring for each distinct layer of the layered material that is to be ablated; and

    the selective ablation of the layered material prepares the layered material for subsequent processing.
