GLASS SHEET CUTTING BY LASER-GUIDED GYROTRON BEAM

摘要

Disclosed are systems and methods for separating a sheet of glass by directing a microwave beam and a laser beam at a sheet of glass to propagate a crack across the sheet. A laser beam spot formed on the glass sheet by the laser at least partially overlaps a microwave beam spot produced on the sheet by the microwave beam and can be used to generate an increased power density in the overlap region, thereby forming a preferential direction for crack propagation.
