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.

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.

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.

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.
