Acoustic emissions expose whether a laser process runs steadily or drifts off course. Fraunhofer IWS develops acoustic monitoring systems that evaluate laser machining directly and instantly. The goal: robust, economical process control to interpret sound emissions in real time and detect deviations immediately. The Dresden Institute showcases a market-ready module at Laser World of Photonics 2025 (June 24–27, Munich) while expanding the approach to laser welding and cutting applications.
Quality assurance in laser micromachining often involves delays, technical effort, and complex post-processing. Typical structures feature micro- and submicron dimensions, requiring time-consuming microscopic inspection. Fraunhofer IWS now provides an industry-oriented alternative:
