Physics & Applications
of High Efficiency
Free-Electron Lasers Workshop

April 11-13, 2018 at the UCLA
California NanoSystem Institute

About the Workshop
  • Increasing the efficiency of Free-Electron Laser amplifier will enable tunable very high peak and average power coherent radiation sources with breakthrough potential in a variety of applications, ranging from TW-class x-ray laser pulses to single molecule imaging, high field QED to EUV sources for lithography, to high energy lasers for industrial and space applications.

    Typical FEL efficiency in the infrared and shorter wavelength are today well below 1 %. A series of recent papers shows the renovated interest to improve the energy extraction from an electron beam beyond the exponential gain saturation level and increase the efficiency up to the 10 % level.

    The workshop brought together the scientists working on this problem to discuss the best methods to increase the efficiency and the resulting applications. Our focus in particular was on optimized undulator tapering schemes, undulator design, simulation techniques, theoretical limits in efficiency and other innovative approaches.

Workshop topics

  • Applications of high average and peak power light sources
