Novel frequency doubled laser platform for atomic quantum technologies

小型化、便携的芯片级时钟和传感器被认为是未来传感器、导航和安全通信系统的核心优先事项。英国皇家工程院（Royal Academy of Engineering）强调了全球卫星导航系统的脆弱性，并建议所有依赖精确时间测量的关键基础设施都应该拥有强大的替代技术。该项目解决了实现这一目标的关键组成部分之一，通过实施DFB激光和为消费应用开发的PPLN技术，生产一种具有成本效益的微型激光技术平台，用于实现用于量子系统和传感器的短波光源。通过利用为picoprojector，平视显示器和近眼显示应用开发的技术，我们将实现量子应用激光技术的阶梯式变化，从而使外形尺寸减少10e5。该项目的愿景是展示一种可扩展的、商业上可行的技术方法，以合作伙伴在将这些技术应用于消费者应用方面的经验为基础，为量子应用生产激光源。

Miniaturised, portable chip-scale clocks and sensors are regarded as central priorities for future sensors, navigation and secure communication systems. The Royal Academy of Engineering has highlighted the vulnerability of global navigation satellite systems and recommends that all critical infrastructures relying on accurate time measurements should have a robust holdover alternative technology. This project addresses one of the key components in achieving this goal by implementing DFB laser and PPLN technology developed for consumer applications to produce a cost effective, miniature laser technology platform for achieving short wavelength sources for use in quantum systems and sensors. By utilising technology developed for picoprojector, head up display and near eye display applications we will achieve a step change in laser technologies for quantum applications resulting in a 10e5 reduction in form factor. The vision of this project is to demonstate a scaleable, commercially viable technological approach to prodcuing laser sources for quantum applications building on the partners experience in applying these techniques for consumer applications.
