QuDOS: Quantum technologies using Diffractive Optical Structures

该项目将开发一种紧凑和简化的装置，用于制备冷原子样品。传统上，激光冷却和捕获原子需要多个光束几何形状，因此，在机械框架内会产生相应的光学元件开销。在这里，我们建议使用一种新颖的方法，其中冷却和捕获所需的所有光束都由光栅芯片反射的单一光束产生。该技术与量子技术有着广泛的相关性，因为它构成了所有原子传感设备（包括重力仪、惯性传感器和时钟）的初级阶段。该项目将斯特拉斯克莱德大学的卓越学术成就与M Squared激光器的工业知识结合起来，利用英国研究基地的这一世界领先的创新技术。我们将通过在工业环境中调试芯片陷阱，提高技术并展示测量能力，使其更接近商业化。

The project will develop a compact and simplified apparatus for the preparation of cold atomic samples. Conventionally, amultiple beam geometry is required to laser cool and trap atoms and, with this, comes a corresponding overhead of opticalcomponents within a mechanical framework. Here, we propose to use a novel approach in which all the beams required forcooling and trapping are generated by a single beam reflected from a grating chip. The technique has wide relevance toquantum technologies as it forms the primary stage for all atomic sensing devices including gravimeters, inertial sensorsand clocks. The project brings the academic excellence of the University of Strathclyde together with the industrial knowhowof M Squared Lasers to exploit this world-leading innovation from the UK's research base. We will take it closer tocommercialisation by commissioning a chip trap within an industrial environment, enhancing the technique anddemonstrating measurement capability.
