We propose to construct a new type of Quantum Cascade Laser (QCL) device, based on anexternal ring cavity. External cavities have already been utilised to expand the availabletuning range of QCL devices. Indeed tuning from around 7 microns up to 11 microns has beendemonstrated from an external cavity QCL (ECQCL). In addition the use of ring cavities toproduce widely tuneable and highly stable single frequency laser light is well known (indeedM Squared produce a state-of-art Titanium:Sapphire laser product based on such a geometry).We propose here to leverage both of these approaches i.e. an external ring cavity, togetherwith M Squared’s proprietary technologies in relation to low noise drive electronics and stableoptical mounting, to produce a proof of concept ring ECQCL with state-of-the-art tuning rangeacross the full infrared waveband (MWIR and LWIR) combined with exemplary spectralpurity. A narrow linewidth ring QCL is an exciting platform technology which will bothenable and significantly improve applications in key areas such as environmentalsustainability, medicines and healthcare as well as defence and security. A product arisingfrom a successful project outcome would be an innovative system offering significantlyimproved performance and functionality and be designed with inherent reliability, thesefeatures will be combined with a intuitive user interface to provide end users with a powerfulnew technology to drive new high value applications.

我们建议构建一种基于外环腔的新型量子级联激光器（QCL）器件。外部空腔已被用来扩展 QCL 器件的可用调谐范围。事实上，外腔 QCL (ECQCL) 已经演示了从约 7 微米到高达 11 微米的调谐。此外，使用环形腔产生广泛可调且高度稳定的单频激光是众所周知的（事实上，M Squared 基于这种几何形状生产了最先进的钛：蓝宝石激光产品）。我们在此建议利用这两种方法，即外部环形腔，以及 M Squared 在低噪声驱动电子器件和稳定光学安装方面的专有技术，以产生证明 概念环 ECQCL 具有跨全红外波段（MWIR 和 LWIR）的最先进的调谐范围以及示例性的光谱纯度。窄线宽环 QCL 是一项令人兴奋的平台技术，它将支持并显着改善环境可持续性、医药和医疗保健以及国防和安全等关键领域的应用。成功的项目成果所产生的产品将是一个创新系统，可显着提高性能和功能，并具有固有的可靠性，这些功能将与直观的用户界面相结合，为最终用户提供强大的新技术来推动新的高价值应用。
