Research projects

Project of LAYERTEC GmbH:

Special optical components for laser-based quantum computers

Project partners:

Universität Hamburg, Technische Universität Kaiserslautern, Fraunhofer ITWM, Data Cybernetics, Menlo Systems GmbH, HighFinesse GmbH, Schäfter und Kirchhoff GmbH, FiberBridge Photonics GmbH, Spectrum Instrumentation GmbH, QUARTIQ GmbH, Otto GmbH & Co KG, Hamburger Hafen und Logistik AG

Project description:

The goal of the RYMAX-project is to build a neutral-atom quantum computer with more than 500 Q-bits based on Ytterbium (Yb)-Rydberg-atoms.
LAYERTEC develops low-loss mirrors and spacers for high-finesse cavities. The goal is to achieve finesse values of 400 000 at 1542 nm and of 300 000 at 578 nm by reliable polishing and coating techniques.
The second goal is to develop fused silica glass cells for the trapping and manipulation of Rydberg-atoms. The glass cells are to be suitable for XHV usage and are to have AR coatings for all necessary wavelengths on the inside and outside.

Project of LAYERTEC GmbH:

Pulse compression optics with high-performance multi-pass cells

Project partners:

Active Fiber Systems GmbH, Jena
Friedrich-Schiller-University Jena, Institute for Applied Physics

Project description:

Multipass cells for pulse compression of high power ultrafast lasers are to be developed. The goal is to achieve light sources that emit extremely short light pulses (τ < 10 fs) with high average power in the wavelength range around 1000 nm. LAYERTEC develops the substrates and coatings of the mirrors for different types of multi-pass cells. The partners will convert the radiation into the EUV range in order to provide the user with a powerful tool for examining extremely small structures (bacteria, viruses, structures on microchips).

Project description:

The aim of the project is the development of laterally structured interference optical components on the basis of high quality coatings. Particular attention is paid to the laser-induced damage threshold of the optics in order to enable the later use of the optics in high-power lasers.
