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.

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、坚固且功耗低，使其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，既可用于地面应用，也可用于空间应用（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日益增长的即插即用组件库中的一个组件。微型ECDL模块将专门为Rb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占有相当大的份额。然而，这是一种通用技术，可以容易地适用于例如其他碱金属系统，其中适当的半导体增益介质是可用的。在该项目中，还将开发定制反馈伺服环路锁定电子设备，这些电子设备将根据特定的最终应用进行设计和优化。
