The aim of this project is to demonstrate an entirely new type of compact laser source by exploiting the unique properties of graphene to realise a solid-state free electron laser.

Pushing the boundaries of research

Free electron lasers (FELs) represent a radical alternative to conventional lasers as they do not have the restrictions of conventional lasers on operating wavelengths, and they are potentially the most flexible, high power and efficient generators of tuneable coherent radiation from the ultra-violet to the infra-red. In a FEL radiation is emitted from an electron beam travelling in a vacuum and passing through an undulatory magnetic field, and the emission wavelength is only determined by the period of the magnetic field and electron beam energy.
