Ever more power per pulse
With their enormous pulse peak powers of several gigawatts and extremely short pulse durations of approximately one trillionth of a second, ultra-short pulse lasers are the perfect tool for high-precision machining of virtually any material. These sources are now well established not only in various fields of research, but also in industrial applications such as drilling and texturing of metal parts for the car industry, or ablative cutting of transparent materials such as the high-strength cover glasses used for optical displays.
However, today the volume of material that can be modified or removed with each laser pulse – and therefore the resulting process throughput – is limited by the available laser pulse energy. This limitation sets the starting point for the new ScULPT project where the partners will be aiming to accelerate process throughput at least proportionally in relation to the increase in laser power.
New beam sources aside, transforming increased laser power into faster machining processes requires additional developments which also form part of the ScULPT project. These include the construction of application-specific machining modules with suitable, fiber-based beam guidance and beam shape adaptations for individual processes, as well as optimized synchronization between laser and beam scanning systems.
Combined expertise of project partners
The project team is formed by corporate partners TRUMPF, SCHOTT and BOSCH as well as the Universities of Jena (Institute for Applied Physics) and Stuttgart (Institut für Strahlwerkzeuge). Between them the project partners combine the necessary expertise to cover the entire value chain from basic research, ruggedization of beam sources, to laser machining of glasses and metals on an industrial scale.
