About the Project

Are you passionate about developing novel research and keen to shape the future of energy transfer technologies in areas such as, high-power laser beams, coherent beam combination, physics of optical beam measurement and control, opto-mechanical designs and engineering?

We are recruiting a motivated PhD candidate to undertake an exciting project within the EPSRC Energy Transfer Technologies Doctoral Training Hub. As a student of the Hub, you will receive an enhanced stipend of £23,237 per year, plus additional funds of £7,000 a year for travel, conferences and research equipment. This project is co- funded by PowerPhotonic Ltd.

 

Project focus

The studentship will focus on Coherent Beam Combination (CBC), which is a modern optical technology enabling multiple single-mode fibre lasers to be spatially tiled or stacked in the near-field, and combined in the far-field at an intended target. The current state-of-the-art laser beam combining modules [1] utilise freeform monolithic array optics in a solution that delivers scaled output power with high efficiency and brightness, in a robust compact module that has size, weight and power factors unattainable using conventional optics.

Critical to the utilisation of this technology, is that all the laser channels are “in phase”, and with the same polarisation state, such that constructive interference occurs in the far-field, creating a high intensity hot spot combining the optical power from all channels. In order to achieve this, the phase and polarisation need to be accurately measured to provide feedback to control the phase of each fibre laser.

This project aims to design and develop future generation laser beam combining modules that will include a novel phase and polarisation detection system that can be integrated into the CBC optical module. The project will start with a critical review of the current methods of detection, assessing the limitations and advantages of each concept in the context of CBC. A new design will be created for a phase and polarisation detection system applicable to a wide range of CBC systems, focussing on scalability, high frame rate and integration with an optical combiner module. This student-led work will be guided by PowerPhotonic engineers, who manufacture CBC combiner modules and have 20+ years of experience in the manufacture and design of freeform optical components.

The opto-mechanical designs of future generation modules will also be developed, building on the expertise at Heriot-Watt University in stress-free and robust mounting techniques, whilst also incorporating the latest manufacturing technologies such as metal additive manufacturing, laser-based bonding of glass-to-metal, and athermal opto-mechanical concepts.
