Abstract
A method of cutting a glass sheet comprising a transparent oxide glass includes directing a laser beam from a middle-infrared (mid-IR) laser source onto a major surface of the glass sheet. A wavelength of the laser beam is tuned thereby adjusting an absorption depth of the laser beam in the glass sheet. The glass sheet is cut using the laser beam.
