EPSRC - Robust beam-shaping and fibre-coupling system for high power diode laser stacks
About the Project
High-power diode laser stacks are widely used in applications ranging from industrial materials processing to pumping of solid-state lasers and emerging photonic systems. However, their inherently poor beam quality and complex spatial emission profiles present a significant challenge for efficient beam shaping and fibre coupling.
This PhD project aims to develop a robust and scalable optical system for transforming the output of high-power diode laser stacks into a beam suitable for efficient coupling into optical fibres. The work will focus on innovative beam-shaping strategies that maximise brightness while maintaining stability and alignment tolerance under high thermal loads.
The project combines experimental optics, optical design, and modelling, offering opportunities to work with high-power laser systems and advanced photonic components. The outcomes will have direct relevance to industrial laser systems, fibre-delivered power applications, and next-generation photonics technologies.
This project also benefits from close engagement with an industrial partner, providing additional perspective on real-world applications and helping distinguish the work in terms of impact and relevance.
