REMOTE - (RuggEd Mirco-ECDL technology for cOld aTom applications in spacE)

该项目的成果是开发一种优化的780 nm微扩展腔二极管激光器（micro- ecdl），其线宽<100 kHz，输出功率超过100 mW。微型ecdl模块紧凑，坚固耐用，功耗低，适用于依赖激光冷却Rb原子的广泛量子技术应用。这包括紧凑、便携和低功耗的原子微波钟、加速度计和旋转传感器，既适用于地面现场应用，也适用于空间（例如低地球轨道）。此外，激光器将成为量子技术研究和开发实验室中不断增长的即插即用组件池中的一个组件。微型ecdl模块将专门为铷的激光冷却而开发，因此在研究市场和预期的早期商业应用中都占有相当大的份额。然而，它是一种通用技术，可以很容易地适应于例如其他碱金属系统，在适当的半导体增益介质可用。在这个项目中，定制反馈伺服环锁定电子设备也将被开发，它将被设计和优化与特定的终端应用。

The outcome of the project is to develop an optimised 780 nm micro extended cavity diode laser (micro-ECDL), which has a linewidth <100 kHz and output power in excess of 100 mW. The micro-ECDL module will be compact, rugged and low power consumption, making it suitable for a wide range of quantum technology applications relying on laser cooled Rb atoms. This includes compact, portable and low-power consuming atomic microwave clocks, accelerometers and rotation sensors both for terrestrial field applications and in space (e.g. low-Earth orbits). Additionally, the lasers will be a component in a growing plug-and-play component pool available for the quantum technology research and development labs.The micro-ECDL module will be developed specifically for laser cooling of Rb and hence serves a substantial fraction of both the research market and the expected early commercial applications. However, it is a generic technology, that readily can be adapted to e.g. other alkali metal systems, where appropriate semiconductor gain media are available. Within this project custom feedback servo loop locking electronics will also be developed, which will be designed and optimised with the particular end applications in mind.
