Project description:

The goal of the UKPiño alliance is to establish a regional competence platform for ultrashort pulse laser technology in the 2 µm range, building on existing competencies and experiences with 1 µm ultrafast lasers. The alliance will develop optical components, beam sources as well as guidance systems. In a total of 7 value chains, potential applications of 2 µm ultrafast technology will also be investigated and further developed.

Within the project UKPiño, LAYERTEC will develop high-performance optical components for 2 µm ultrafast lasers and beam guidance systems. Special attention will be paid to the required measurement technology. It is planned to set up measurement stations for the highly accurate determination of reflectance (using cavity ring-down spectroscopy), absorption losses, laser-induced damage threshold (LIDT) and group velocity dispersion (GDD) of the optics.

Project of LAYERTEC GmbH:

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 description:

The aim of the QUASENS project is to demonstrate an optical clock with a stability better than 1 x 10^-15 over several hours of averaging time, in the form of a 19" device. The QUASENS clock is based on atom interferometry using a thermal Sr atom beam.

LAYERTEC will develop mirror systems and resonator substrates for high-finesse resonators. The goal is to produce mirrors with a reflectance of R = 99.999 % (resonators with finesse 314,000) at 1542 nm and a transmission of 5 ppm. Additionally, resonators for 689 nm with a finesse of 200,000 (R = 99.9984 %, T = 5 ppm) will be developed. Together with Menlo Systems, further resonator concepts will be investigated, focusing on stability against mechanical vibrations and minimal space requirements.

LAYERTEC will also develop micro optics for the new laser diodes at 689 nm in collaboration with the Ferdinand-Braun-Institut and will work on the optics for the atom interferometer in collaboration with Humboldt-Universität.

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.
