More Information
Summary:Methods of separating a glass web include exposing a separation path on the glass web to a laser beam that produces thermal stress along the separation path without damaging the glass web. The methods further include redirecting a portion of the laser beam to create a defect on the separation path while the separation path is under thermal stress produced during the exposing the separation path on the glass web to the laser beam, whereupon the glass web separates along the separation path in response to creating the defect. Apparatus are further provided for separating a glass web with at least one laser beam generator that produces a laser beam to heat a separation path and a mirror configured to reflect an end portion of the laser beam to create a defect at a location of the separation path on the glass web.
