New fibre-optic lasers that can deliver high-power beams efficiently over long distances are to be developed by a new Royal Academy of Engineering Research Chair at the University, with support from SPI Lasers.
Professor Michalis Zervas of the University’s Optoelectronic Research Centre (ORC), will build on his years of research in high-power fibre lasers to develop the next generation of laser technology, which will exploit novel features of fibre lasers to be used in manufacturing.
The SPI Lasers / Royal Academy of Engineering Chair in Advanced Fibre Laser Technologies for Future Manufacturing will develop new passive and active fibre technologies, with precisely engineered materials to make fibre-optic lasers ‘smarter’, more stable and efficient. This includes using novel composite materials for both the inner core and the outer cladding of the fibres, as well as doping – deliberately introducing impurities into the fibres to enhance their performance.
The new technologies will enable the scaling up of powerful fibre lasers with added functionality but a smaller footprint. This allows precise control over the shape of the laser beam, its polarisation, and wavelength – features that can be exploited in new laser manufacturing tools for precise welding, cutting and additive manufacturing.
Professor Zervas said: “I am delighted to have been awarded this prestigious Research Chair and the opportunity that comes with it to work closely with the Royal Academy and SPI Lasers to develop the next generation of industrial laser manufacturing tools.”
