Novel compact narrow linewidth laser for gravimetric and quantum applications

拟议项目的重点是开发将量子传感应用开发到真实的世界所需的子系统，以及子系统供应链的开发。目前的项目重点是1）微型集成高稳定性激光源的开发，2）适用于恶劣环境下ASIC集成的相关数字稳定电子器件的开发。在该项目期间，将开发一种新型的集成激光源，并在涉及原子和分子光谱学的专门实验中充分表征。与此同时，将开发确保超高激光稳定性所需的专用数字电子设备，并具有空间资格的长期前景，以使量子传感器能够搭载在空间平台上。最后，新的激光系统和相关的数字集成电子设备将在为重力传感而开发的冷铷原子干涉仪上进行评估。

The proposed project focuses on developing sub-systems required for the development of quantum sensing applications into the real world, and the development of a sub-system supply chain. The current project focusing on 1) the development of miniature integrated high stability laser sources, 2) the development of associated digital stabilization electronics suitable for ASICs integration in harsh environments. During the project a novel integrated laser source will be developed and fully characterized in purposed built experiments involving atomic and molecular spectroscopy. At the same time, dedicated digital electronics required to ensure ultra-high laser stability will be developed with the long term prospect of space qualification to enable quantum sensors on-board space platforms. Ultimately the novel laser system and associated digital integrated electronics will be evaluated on a cold rubidium atoms interferometer developed for gravity sensing.
