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 productive 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 advantages 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.

Research Objectives

- Design and optimise optical architectures for beam shaping of diode laser stacks
- Develop robust fibre-coupling strategies for high-power, multimode sources
- Model beam propagation and transformation using numerical techniques
- Experimentally validate system performance and efficiency
- Investigate thermal and mechanical stability of optical configurations
- Evaluate system scalability for industrial deployment

Applicants should have, or expect to achieve, at least a 2.1 honours degree or a master’s (or international equivalent) in a relevant science or engineering related discipline.
