Multi-beam systems are a key technology to increase the total converted laser power and significantly boost productivity. Therefore, Fraunhofer ILT together with Pulsar Photonics has developed an USP multi-beam system in a roll-to-roll machine. The optical system generates 24 beamlets which are simultaneously deflected by 4 galvo-scanners to continuously structure electrode material of 300 mm bandwidth for efficient battery manufacturing.

A new setup for Direct Laser Interference Patterning DLIP enables the functionalization of glass surfaces at sub-micro level. Tailored spatial periods with periodic patterns down to 200 nm show amazing optical effects for anti-counterfeiting without using color pigments or enable spatial alignment of cell elongation of pluripotent stem cells.

Thin films with micrometer-small holes are in demand for a variety of applications, such as filters in environmental or medical technology. The short wavelength of UV ultrashort pulse laser radiation enables drilling of micrometer holes with high precision and minimal thermal impact.

Scalable quantum processors based on trapped ions require novel trap designs which enhance the performance and reliability and increase the integrability for optical addressing. Nevertheless, a simple yet precise fabrication must be ensured. In the project “IQuAn” we demonstrated the fabrication of an ion trap with 3D structures in fused silica using our two-step process Selective Laser-induced Etching SLE.

The versatility of ultrafast laser radiation is extended by a precision polishing process based on tailored surface melting.

The shorter wavelength offers tighter focusing and increased absorption that enables high precision structuring. The prototype UV micro scanner achieves excellent quality and repeatability for surface structuring with feature sizes down to 400 nm.

First test of the new optical module with 8 flexible multibeams, boosting process performance more than a factor of 4 already! In the next months, 7 identical optical modules will follow to complete the 64 flexible multibeam tool. The demonstrator machine is equipped with a 1 kW ultra short pulsed laser and designed to significantly increase productivity of laser microstructuring.

In the project “FOCUS” we develop a sensor-based position detection and control system to combine the best of two worlds: The flexibility of a commercial, cost-effective 6-axis robot and the precision of ultrashort pulsed microstructuring.

One of the key technologies to increase productivity of laser micromachining and maintain the high level of surface quality is multibeam processing. The multibeam technology has already found its way into industrial production for consumer electronics or medical products. Here, the generation of flexible surface structures for embossing tools or micro-drillings for filter applications with feature sizes down to 1 µm have been demonstrated.
