Free-Electron Lasers: Status and Applications

摘要

A free-electron laser consists of an electron beam propagating through a periodic magnetic field. Today such lasers are used for research in materials science, chemical technolgoy, biophysical science, medical applications, surface studies, and solid-state physics. Free-electron lasers with higher average power and shorter wavelengths are under development. Future applications range form industrial processing of materials to light sources for soft and hard x-rays.
