POLARIS: high POwer, phase-locked LAseRs for atom InterferometerS

原子干涉仪是许多量子技术的核心，能够高精度测量冷原子云的影响，例如运动，重力，时间，磁场和电场。这些能力具有广泛的应用，包括卫星自由导航、金融时间戳、医学成像和地质勘测。该项目的目的是开发一种高性能激光器，用于创建，操纵和探测原子干涉仪的叠加态。通过提供高功率低相位噪声激光器，传感器的能力得到了提高。该系统将在惯性传感上进行演示，惯性传感需要高功率，对相位噪声特别敏感。基于量子的惯性传感单元可以为运输和采矿中使用的高精度无卫星导航铺平道路。

Atom interferometers are at the heart of many quantum technologies, enabling high precision measurements of influences on clouds of cold atoms, such as motion, gravity, time, magnetic and electric fields. These capabilities have a wide range of applications including satellite free navigation, financial time stamping, medical imaging and geological surveying. The aim of this project is to develop a high performance laser that will be used to create, manipulate and probe the superposition state of the atom interferometer. By delivering a high power low phase noise laser the sensors capabilities are increased. The system will be demonstrated on inertial sensing that requires high powers and is particularly sensitive to phase noise. Quantum based inertial sensing units could pave the way to high precision satellite-free navigation for use in transport and mining.
