The University of Amsterdam hosts the Strontium Quantum Gases group of Florian Schreck, which coordinates AQuRA. The group uses strontium quantum gases to study quantum many-body physics and for precision measurement. Besides the AQuRA project, five projects are pursued: the Quantum Delta NL strontium optical lattice clock and sensing testbeds, continuous superradiant clocks developed under the iqClock project, the creation of ultracold RbSr ground-state molecules, a continuous atom laser and Sr tweezers for quantum computation and simulation. The atom laser project delivered the first continuous-wave Bose-Einstein condensation, a continuous-wave atom laser with fully reflective mirrors. The technology developed as part of the atom laser and clock projects forms the basis of the Amsterdam contributions to AQuRA.
Within AQuRA the University of Amsterdam will coordinate the project and outreach activities as well as develop the electronic and optical distribution and control hardware and software for operating the physics package. More information... |

Vexlum manufactures high-power laser systems based on the vertical-external-cavity surface-emitting laser (VECSEL) concept to address applications in quantum technology, industry, and medicine. The Vexlum team has been a leading development group in the area of VECSEL technology for more than a decade. Our laser platform (i.e. existing "VALO" product line) combines a semiconductor gain architecture with efficient intracavity wavelength conversion, offering the broadest wavelength coverage from UV to near infrared with low-noise single-frequency operation, watt-level output power, and excellent beam quality. Benefiting from a superior SWaP-c compared to established laser technologies and the in-house semiconductor fabrication, VALO lasers target the industrial scaling of quantum technology applications exploiting ion- and atom-based architectures.
Within AQuRA Vexlum team will develop and supply a new generation of high power 461nm lasers needed to laser cool the strontium atoms for the optical lattice clock (Tasks). More information... |
