Heriot-Watt scientist secures £2.5m to develop new ultrafast laser technologies

Date Announced: 14 Mar 2024

Edinburgh,UK -- An ultrafast laser scientist at Heriot-Watt University has secured a prestigious £2.5 million engineering award for research that could lead to breakthroughs such as X-rays that image nature with unprecedented detail and speed and the development of microscopic mechanical devices.

John C. Travers, Professor of Physics at Heriot-Watt University and director of the Laboratory of Ultrafast Physics and Optics, pictured above, has been awarded a Royal Academy of Engineering Chair in Emerging Technologies. The award aims to support ‘global research visionaries’ and provides 10 years of funding for emerging technologies with high potential to deliver economic and social benefits to the UK.

Professor Travers’ research uses wave formations that were discovered in the Union Canal next to Heriot-Watt’s Edinburgh campus 200 years ago by Scottish civil engineer John Scott Russell. The Heriot-Watt team uses these waves – as light waves rather than water waves – to create ultrafast optical pulses that are a million billionth of a second in duration. This is a measurement of time known as an ‘attosecond.’

The process creates a high-performing form of bright ultraviolet light that has multiple transformational applications in sectors including manufacturing, electronics, artificial intelligence and drug discovery.

“The Royal Academy of Engineering award is fantastic because it provides long-term funding to underpin our research,”  said Professor John C. Travers, of Heriot-Watt University.

“If we can create these extremely short pulses of X-ray or electron beams, it means we can image, probe and control matter on the smallest possible spatial scale – on a tiny, microscopic scale – and also on the fastest possible timescale – simultaneously.

“This can lead to advances like new materials, new drug discovery and more powerful computer chips – which underpin everything we do, from our mobile phones to artificial intelligence,” he added.

“It will also mean materials can be processed to produce much smaller structures, so you'll be able to manufacture micro machines or microscopic mechanical devices with great precision.”

Last year’s Nobel Prize in Physics was awarded for a breakthrough in attosecond science that enabled things to be measured over extremely fine timescales – like flash photography, but a billion times faster. But it is not currently possible to simultaneously measure things at extremely small spatial scales, Professor Travers explained.

A key feature of the ultraviolet system Professor Travers has invented is its tabletop size. This is tiny compared to the building-sized, multi-billion dollar machines currently used to generate ultraviolet and X-ray light sources, Professor Travers said. His system is already being used in 14 different labs around the world, including healthcare and semiconductor settings.

The funding that Professor Travers has been awarded focuses on developing ultrafast, bright ultraviolet X-ray and electron beams – which are both forms radiation – energy that travels through space at, or close to, the speed of light.

“The Royal Academy of Engineering award is fantastic because it provides long-term funding to underpin our research,” Professor Travers said. “We will be able to recruit new academic staff at the assistant professor level and also build a centre of excellence in this area. So we’re not just boosting what we do, but actually recruiting more expertise from around the world.”

There are currently around 15 people in Professor Travers’ research team, including PhD students, postdoctoral researchers and junior staff members. Heriot-Watt University has “first mover” advantage in this field, Professor Travers added.

The Royal Academy of Engineering advances and promotes excellence in engineering. Its Chair in Emerging Technologies scheme is funded by the UK Department for Business, Energy and Industrial Strategy and has awarded more than £100 million to 43 Chairs since 2017. Professor Travers is one of four academics receiving a total of £10 million in this latest funding round.

Dr Andrew Clark, Executive Director of Programmes at the Royal Academy of Engineering, said: “I am excited to announce this latest round of Chairs in Emerging Technology. The mid-term reviews of the previous rounds of Chairs are providing encouraging evidence that long-term funding of this nature helps to bring the groundbreaking and influential ideas of visionary engineers to fruition. I look forward to seeing the impacts of these four exceptionally talented individuals.”
