Advances in global digitalization are stressing the demand for highly individualized glass components in applications such as consumer electronics, automotive construction, and telecommunications. Conventional methods, such as mechanical scribe and break, cannot meet the high requirements for novel glass components without costly post-processing since they either lack flexibility or generate a high concentration of defects. Here, the tool “laser” makes a contactless, efficient and highly flexible glass processing technology possible. For this, the laser radiation for a specific application of the glass component must be customized. Fraunhofer ILT is developing innovative spatial and temporal beam shapes and evaluating their potential for specific applications.
