UV4QT

Highly Efficient Frequency Doubling into the UV Range for Quantum Technologies

Trapped ions are a key resource of modern quantum technologies. They are used, among other things, in quantum computers, optical atomic clocks and high-precision sensors. Many of these applications require laser light in the ultraviolet (UV) spectral range, which is currently generated with considerable effort and limited efficiency. The resulting maintenance requirements and downtimes represent an obstacle to reliable continuous operation.

The QVLS-iLabs project UV4QT is developing compact and efficient frequency doublers for the reliable generation of UV laser light. For this purpose, novel walk-off-compensated crystals as well as alternative materials are being investigated that enable significantly higher efficiency. This reduces the required laser power, which decreases the strain on the components and increases the lifetime of the systems.

In addition, a particularly compact and long-term stable resonator design is being researched. The goal is to realize robust demonstrators and significantly reduce maintenance and downtime. The project thus makes an important contribution to the integration of key photonic components and the reliability of future quantum technologies.
