NX Micro COTS laser system for quantum gravity gradiometry

用于量子重力梯度测量的NX Micro COTS激光系统项目汇集了一个学术和行业专家团队，以增强量子技术的现有技术能力，并加速定位、导航和授时（PNT）传感器的商业化进程。该项目的关键成果是一个最先进的激光系统，用于控制量子重力传感器中原子样品的量子态。该激光系统基于固态激光技术，与其他激光源相比具有关键优势。目前的固态量子激光器体积庞大，价格昂贵，虽然它们为研究目的提供了一个很好的解决方案，但它们的可扩展性有限，因此很难在集成和产品开发项目中得到证明。其他技术，如分布式反馈（DFB）激光器提供了一个更经济的选择，但它们缺乏固态平台的优越性能。我们的提议使二极管泵浦固态技术更接近DFB激光器的价格点，同时也提供了现有固态激光器提供的所有优势。此外，我们与赫瑞瓦特大学和格拉斯哥大学合作，将这些激光器集成到一个封装的系统级解决方案中，为现有的量子传感器制造商提供交钥匙产品，在开发过程中节省成本、空间和复杂性。所提出的解决方案在功能上是独一无二的，而且整个系统的成本只是现有产品的一小部分。我们将与Delta g合作，在现有的重力梯度地图匹配能力中验证和测试我们的系统。

_The NX Micro COTS laser system for quantum gravity gradiometry_ project brings together a team of academic and industry experts to enhance existing technical capabilities within quantum technologies and accelerate the commercialisation process of Positioning, Navigation, and Timing (PNT) sensors. The key deliverable of this project is a state-of-the-art laser system to control the quantum state of a sample of atoms within a quantum gravity sensor. The laser system is based on solid-state laser technology, which shows critical advantages compared to other laser sources. Current solid-state quantum lasers are large and expensive, and whilst they provide a good solution for research purposes, they promise limited scalability and hence are hard to justify in integration and product development projects. Other technologies, such as distributed feedback (DFB) lasers provide a more economical option but they lack the superior performance of a solid-state platform. Our proposal brings diode-pumped solid-state technology much closer to the price point of a DFB laser, while also providing all the advantages existing solid-state lasers offer. Furthermore, we work with Heriot Watt University and Glasgow University to integrate these lasers into a packaged, system-level solution, providing a turn-key product to existing quantum sensor manufacturers, saving costs, space and complexity in their development process. The proposed solution is unique in terms of its functionality and the overall system costs a fraction of existing products. We will validate and test our system in existing gravity gradient map matching capabilities, in collaboration with Delta g.
