QuDOS: Quantum technologies using Diffractive Optical Structures

该项目将开发一种用于制备冷原子样品的紧凑和简化的装置。传统上，需要多束几何形状来激光冷却和捕获原子，并且，与此同时，在机械框架内的光学组件的相应开销也随之而来。在这里，我们建议使用一种新的方法，其中所有的光束所需forcooling和陷阱产生的一个单一的光束从光栅芯片反射。该技术与量子技术有着广泛的相关性，因为它形成了所有原子传感设备的初级阶段，包括重力仪，惯性传感器和时钟。该项目将斯特拉斯克莱德大学的学术卓越与M Squared Lasers的工业专业知识结合在一起，以利用英国研究基地的这一世界领先的创新。我们将通过在工业环境中调试芯片陷阱，提高技术和展示测量能力，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.
