DPSS Laser stabilised at 813nm for Sr Clock Application (LQT813)

量子技术计划的重点是将量子传感器和量子设备推向市场和最终用户。量子传感器在灵敏度上提供了无可置疑的性能优势，并且在制造更紧凑的系统方面已经取得了一些进展。但是为了真正的和广泛的应用，需要在这些系统的尺寸，重量和功率（SWAP）以及坚固性方面进行实质性的改进。一个稳定的激光器是量子量子传感器的基础，用于定时、重力和磁场。它们也是安全通信、量子计算和量子成像的关键。除了SWAP之外，这样的系统还需要涵盖波长范围，而这些波长范围目前还不太容易获得。在这个项目中，我们的目标是开发一个与当前商用激光器（例如M2和Coherent的Ti:S激光器）的光学性能相匹配的激光平台，但价格点与外腔二极管激光器（ECDL）相当。我们计划证明这样的平台可以在许多其他难以进入但至关重要的线路上运行。这样的发展将是QT从研究界转向国防、空间和消费市场道路上的关键一步。在短期内，经济机会将来自供应链建设活动，提供新的世界领先的基础技术。目标激光平台将使我们在全球QT研究的开发中跃进一步。世界各地的研究小组经常梦想拥有交钥匙系统。从中期来看，英国将成为早期小批量、高价值QT应用（金融、空间）的首选供应商，从长期来看，我们将处于利用QT向消费市场不可避免的过渡的理想位置。该项目所做的工作也将对航天部门产生复杂的影响。简而言之，该项目将使体积、功率、尺寸和成本减少一个数量级以上，而不会失去其性能和稳健性。这些组件是非常关键的，从而跨越英国QT的发展和商业化。

Quantum technology initiative is focused on bringing quantum sensors and quantum devices to market and end users. Quantum Sensors offer unquestioned performance advantages in sensitivity and some steps have been made at making more compact systems. But for genuine and widespread applications substantial improvements need to be made in size, weight and power ('SWAP') and ruggedness of these systems. A stable laser is the bedrock for quantum quantum sensors for timing, gravity and magnetic field. They are also the key to secure communication, quantum computation and quantum imaging. In addition to SWAP, such systems need to encompass the wavelength ranges, which are not so easily accessible today. In this project, we aim to develop a laser platform matching the optical performance of current commercial lasers (e.g. Ti:S laser from M2 and Coherent) in a footprint but with a price point comparable to the external-cavity diode laser (ECDL). We plan to demonstrate that such a platform can operate on many otherwise difficult-to-access but crucial lines. Such a development will be a critical step on the road to the translation of QT from the research community to the defence, space and consumer market. In the short term, economic opportunity will arise from the supply chain building activities, delivering novel world leading underpinning technologies. The aimed laser platform will leap frog us in the exploitation of global QT research. The research groups world wide often dream of having turn-key systems. In the medium term, the UK will become the supplier of choice for early low-volume, high-value applications of QT (finance, space) and in the long- term we will be ideally placed to exploit the inevitable transition of QT to the consumer market. The work done in the project will also have a tangle impact on the space sector. In brief, this project will bring reduction in volume, power, size and cost by over an order of magnitude and this will done without losing their performance and robustness. These components are enormously critical, thereby leap frogging the UK QT development and commercialisation.
