Laser scoring with flat profile beam

摘要

Disclosed are systems and methods for scoring glass sheets. A laser beam can be generated having a substantially uniform peak energy density along at least a portion of its length. The laser beam is moved across the glass sheet to create a score line. Further, the glass sheet can be separated along the score line. In some aspects, the laser beam is bimodal and comprises approximately 60-70% TEM00 mode and approximately 30-40% TEM01* mode.
