This project aims to develop two prototype optical beam shaping systems, culminating in the demonstration of new high-power optical fibre amplifiers. This novel ability to control all the properties of light enables the generation of optical beams that were only theoretical ideas but never previously implemented experimentally. This advanced technology can potentially open new ways in which objects can be probed using light. Expected outcomes include the creation of an optical platform that the optical community at large may utilise for their specific applications. Besides the intellectual property benefits of such optical devices directly, this project should bridge the gap between the developed knowledge and commercial opportunities.Read moreRead less

This project aims to create devices to measure and manipulate the spatial and temporal properties of light. The ability to control or measure the spatial and/or temporal properties of light is a fundamental feature of many applications, including biomedical imaging, astronomy, telecommunications, high-power lasers and quantum computing. This project will develop five prototype systems to control the spatiotemporal properties of light in ways that were previously not possible. This would affect fundamental and applied applications where the inability to sufficiently control light’s spatial and/or temporal properties is an impediment. Examples include imaging deep into ‘opaque’ objects such as human skin or brain, high-power lasers for material processing and manufacturing, optical telecommunications and quantum computation.Read moreRead less
