Novel compact narrow linewidth laser for gravimetric and quantum applications

点击翻译按钮获取中文摘要

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.
