Optical clocks offer superior performance (e.g. >100 times greater accuracy) over alternative atomic clock technologies. They are required in satellite free navagation, timing signals for financial trading as well as scientific research amongst many other potential applications. However, existing optical clocks are large, complex & expensive and have not so far met the needs of these markets, one of the reasons is the lack of suitable laser sources for field deployment. In this project we will develop underpinning subsystems of optical clocks, frequency-stabilised laser systems, using GaN external cavity diode lasers.

与替代原子钟技术相比，光学时钟具有卓越的性能（例如，精度提高 100 倍以上）。它们在卫星自由导航、金融交易定时信号以及科学研究以及许多其他潜在应用中都需要。然而，现有的光学时钟体积庞大、复杂且昂贵，目前还不能满足这些市场的需求，原因之一是缺乏适合现场部署的激光源。在这个项目中，我们将使用 GaN 外腔二极管激光器开发光学时钟、稳频激光系统的基础子系统。
