Next-generation femtosecond fibre-laser CPA sources and their applications
Supervisor: Professor D Richardson FRS
Co-supervisor: Dr Jonathan Price
This PhD project will address the pressing challenge of significantly increasing pulse energy from a single fibre laser by incorporating newly created fibres from both the Optoelectronics Research Centre (ORC) fabricators and collaborators to significantly advance the state-of-the-art.
Applications of femtosecond and picosecond pulse lasers are driving the forefront of laser research. This close link was recognised by the 2018 Nobel Prize in Physics for the development of chirped-pulse-amplified (CPA) lasers. Achieving a significant increase in the pulse energy from a single fibre laser is now reaching fundamental limitations set by nonlinear interactions in the fibres.
We are looking for applicants with a background in physics, material sciences or engineering to develop the technology needed to support future industry. There is ample scope for an ambitious student to emerge as world-leading scientist with an exceptional grounding as a potential research leader.
This project will make use of our new computer-controlled ‘tailored’ pulse-shaper, which by acting in the spectral (Fourier) domain, can dynamically apply the required phase/amplitude. This advanced laser capability will be applied by our collaborators in nonlinear imaging (bio-sciences), material surface processing (industry) and to better understand the physical processes in the fibres.
Full tuition funding, plus, for UK students, an enhanced stipend of £18,000 tax-free per annum for up to 3.5 years. www.orc.southampton.ac.uk/phd_funding. EU students with no external funding can contend for a small number of competitive scholarships. Students from overseas who have secured some external funding are also encouraged to apply.

About the Optoelectronics Research Centre
The ORC has been leading the world in optical fibre technology research for the past 50 years. With over 90 state-of-the-art laboratories and 200 researchers working in all areas of photonics, the ORC provides an outstanding interdisciplinary environment for students to grow. Its cluster of 12 photonics spin-out companies provides a natural career path for PhD graduates.
The group has an excellent track record of publishing in high profile research journals and leading international conferences. Its former PhD and postdoctoral researchers have made successful careers in universities worldwide or as industry scientists and business leaders.
In the first year of your PhD a structured training programme runs alongside the research project, providing a gradual transition from a taught degree to open-ended research. Students present their work at conferences worldwide, first-author papers in leading academic journals and emerge with skills at the forefront of glass and fibre optics research https://www.youtube.com/watch?v=N2_6yNQamkU.
Entry requirements: first or upper second-class degree or equivalent
Closing date: applications are welcome throughout the year.
Duration: typically three and a half years (full-time)
Assessment: reports at the 8 and 16-month stage and an oral examination to determine progression to PhD, which is awarded after thesis submission and viva voce examination
Start date: typically October (although later starts might be acceptable)
