Abstract
Systems and methods for processing, selectively ablating, and singulating layered materials. According to some embodiments, methods for selectively ablating a layered material may include selectively varying a wavelength of at least a portion of a primary ultrafast laser beam to create a secondary ultrafast laser beam with a second wavelength, the primary ultrafast laser beam being configured to ablate a layer of the layered material, the secondary ultrafast laser beam being configured to ablate an additional layer of the layered material and applying the first and second ultrafast laser beams to the layered material to create a singulated product.
