Quantum Free Electron Lasers: Current situations and prospects

Plenary track > Science and Technology based on XFEL

Quantum free electron lasers (Q-FELs) provide the opportunities to realize high-gain x-ray devices on the scale of a university laboratory with unprecedented small bandwidths at both transverse and longitudinal coherence. Compactness of Q-FELs arises from the use of laser pulses as optical undulators, which reduce undulator period to sub-micrometers and electron energy to a few ten MeV for the production of coherent x-ray pulses. Several academic teams are carrying out relevant research work in the world. Since two years ago, we also start to focus on Q-FELs and form a joint research team. Here, we briefly introduce the development history and current situation of Q-FELs, as well as the experimental challenges it faces. The main members of our joint team and the important progresses our team made are also introduced briefly. We hope more teams will join in our work and further promote the development of Q-FEL.
