This Innovate UK project is aimed at developing compact DFB lasers at 780.24 nm that are locked using a MEMS Rb cavity and an interferometer to an atomic transition in 87Rb atoms. The system is the basis for atomic clocks, inertial sensors, rotation sensors, quantum navigators, magnetometers and electrometers. The project pulls together the University of Glasgow and the University of Birmingham with the UK companies M Squared Lasers, Kelvin Nanotechnology and Optocap to build a UK supply chain for miniature lasers systems for practical and portable cold atom systems. The technology being developed can also be used for chip scale cold atom systems that ultimately could be in ever mobile phone.

这个创新英国项目旨在开发 780.24 nm 的紧凑型 DFB 激光器，使用 MEMS Rb 腔和干涉仪锁定 87Rb 原子中的原子跃迁。该系统是原子钟、惯性传感器、旋转传感器、量子导航器、磁力计和静电计的基础。该项目将格拉斯哥大学、伯明翰大学与英国公司 M Squared Lasers、Kelvin Nanotechnology 和 Optocap 联合起来，为实用和便携式冷原子系统建立微型激光系统的英国供应链。正在开发的技术还可用于芯片级冷原子系统，最终可能出现在手机中。
