项目摘要

The objective of the project is to develop beyond state-of-the-art highly stabilised laser sources whose high performance coupled with cost-effectiveness and compact size enhances access of researchers/technologists into a broad range of Quantum Technologies (QTs) and provides the basis for integration into future commercial Quantum Technology instrumentation. Diode-pumped Alexandrite laser technology will be developed in a commercial platform with precision highly-stabilised wavelength tunablility over a broad band and sub-MHz ultra-narrowlinewidth control, as required for Quantum Technology applications. The ability to directly diode-pump the vibronic solid-state Alexandrite laser provides the basis as a significantly lower cost, more compact replacement to the current mainstream titanium-sapphire laser technology. Due to direct diode-pumping the Alexandrite technology has excellent power scaling potential to the multi-W and multi-ten-Watt power level addressing future demands in commercially-scaled QT systems.The project brings together commercial partner, M-Squared Lasers (MSL) and academic team at Imperial College London (IC). The IC academic team are the world-leading group in diode-pumped Alexandrite lasers, with world-record demonstrations of highest power (>26W), highest efficiency, and broadest tuning range, and notable first Q-switching and cavity-dumped Q-switching developments made for satellite-based lidar application for the European Space Agency (ESA). MSL bring a track record for innovative commercial laser development and award-winning laser products. The scientific and technical expertise of the IC group combined with the engineering, commercial and market knowledge skills of MSL provides a solid basis to accelerate the translation of Alexandrite laser technology from research laboratory to a new specification and commercial product platform to address the growing needs of Quantum Technologies.An Alexandrite Ring Laser (ARL) pre-prototype system will be designed with wavelength tuning and narrowlinewidth control, and significant power target, leading to a first pre-prototype ARL to be built and performance characterised at Imperial (Milestone 1). A second pre-prototype ARL system will be built at MSL to provide further performance optimisation of specification and operation as a demonstrator for QT applications (Milestone 2). Imperial will modify the first pre-prototype for demonstration and validation of feasibility of power scaling (Milestone 3). MSL will couple their pre-prototype to QT application with demonstration to potential users (Milestone 4). Market study and Technology Roadmap will be made for the development of the Alexandrite laser technology and its commercialisation (Milestone 5).The successful outcome of this project will lead to new cutting-edge laser technology with highest performance and low cost/compact format that will enable current and future Quantum Technology processes and applications including cooling, atomic clocks and gyroscopes for navigation; gravimeters for military and earth observation; secure communications etc.

该项目的目标是开发超越最先进的高度稳定的激光光源，其高性能与成本效益和紧凑的尺寸相结合，增强了研究人员/技术人员进入广泛的量子技术(QTS)的机会，并为集成到未来的商业量子技术仪器提供基础。根据量子技术应用的要求，二极管泵浦的紫翠宝石激光技术将在商业平台上开发，在宽带上具有高精度的高度稳定的波长可调谐，并具有亚兆赫超窄线宽控制。直接二极管泵浦振动固态紫翠宝石激光器的能力为替代当前主流钛蓝宝石激光器技术提供了成本显著更低、更紧凑的替代产品。由于直接二极管泵浦，亚历山大石技术具有极佳的功率扩展潜力，可达到多瓦和十瓦的功率水平，满足商业规模QT系统的未来需求。该项目汇集了商业合作伙伴M-Squared激光器(MSL)和伦敦帝国理工学院(IC)的学术团队。IC学术团队在二极管泵浦的亚历山大石激光器方面处于世界领先地位，展示了最高功率(&gt；26W)、最高效率和最宽调谐范围的世界纪录，并为欧洲航天局(ESA)的卫星激光雷达应用首次开发了引人注目的Q开关和腔倾倒Q开关。MSL在创新的商业激光开发和屡获殊荣的激光产品方面取得了良好的成绩。集成电路集团的科学技术专长与MSL的工程、商业和市场知识技能相结合，为加快紫翠宝石激光技术从研究实验室向新规格和商业产品平台的转化提供了坚实的基础，以满足量子技术日益增长的需求。紫翠宝石环形激光器(ARL)预原型系统将设计具有波长调谐和窄线宽控制功能，并具有显著的功率目标，导致将建造第一个预原型ARL，其性能表征在Imperial(里程碑1)。第二个预原型ARL系统将在MSL建造，以提供进一步的规格和操作性能优化，作为QT应用程序的演示(里程碑2)。Imperial将修改第一个预原型，以演示和验证功率扩展的可行性(里程碑3)。MSL将把他们的预原型与Qt应用程序结合起来，并向潜在用户进行演示(里程碑4)。市场研究和技术路线图将为亚历山大石激光技术的发展及其商业化(里程碑5)制定。该项目的成功成果将导致具有最高性能和低成本/紧凑格式的新的尖端激光技术，使当前和未来的量子技术工艺和应用能够实现包括用于导航的冷却、原子钟和陀螺仪、用于军事和地球观测的重力仪、安全通信等。
