Separating And Structuring Of Brittle Material By The Use Of Laser Radiation

This article discusses the latest developments and possibilities of industrial processing brittle materials with a laser beam. Conventional methods such as scoring with metal or tungsten carbide wheel, diamond, etc, followed by breaking, have long been established in glass processing. These methods have reached the limits of their technical and technological development and defy further improvement. Certain drawbacks, such as the production of glass dust or micro cracking at the separating edge, cannot be avoided. These and other disadvantages can be compensated with laser processing.
