MagGaN: Magnesium-clock frequency-stabalised GaN-diode lasers

光学时钟提供了优越的性能（例如，比原子钟技术精度高100倍）。它们在卫星自由导航、金融交易的定时信号以及科学研究等许多其他潜在应用中都是必需的。然而，现有的光学时钟体积大、结构复杂且价格昂贵，迄今为止还不能满足这些市场的需求，其中一个原因是缺乏适合现场部署的激光源。在这个项目中，我们将开发光学时钟的基础子系统，频率稳定的激光系统，使用GaN外腔二极管激光器。

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.
