1. A method of cutting a glass sheet comprising a transparent oxide glass, the method comprising:
directing a laser beam from a middle-infrared (mid-IR) laser source onto a major surface of the glass sheet;
tuning a wavelength of the laser beam so as to adjust an absorption depth of the laser beam in the glass sheet;
cutting the glass sheet using the laser beam; and
arranging a transparent cover substrate on the major surface of the glass sheet, the cover substrate having a transmission percentage that is greater than a transmission percentage of the glass sheet in a mid-IR wavelength range; and
directing the laser beam through the cover substrate.
