In the field of laser materials processing Jenoptik has progressed the thermal laser beam separation process (TLS) with its JENOPTIK-VOTAN TM G laser system up to the mass-production ready stage. Brittle materials such as glass, ceramics and semiconductors (wafers) are heated via a laser beam and then quickly cooled. The powerful stresses that occur in the material as a result create a defined crack along the laser beam's direction of movement. In comparison with conventional, abrasive technologies the impressive features of the new process are the micro-crack free edges it produces, higher breaking strength and the fact that it simultaneously prevents contamination. It is a contactless process and because of the special active principle operates totally particle-free. In addition, with the thermal laser beam separation the process speed is increased by up to 300 percent.
With the thermal laser beam separation (TLS) Jenoptik has entered into a new growth area in addition to the solar industry.
