摘要：
A high-current relativistic electron beam propagating through a plasma causes local depression in plasma electron density to attain charge neutralization. The plasma duct thus formed guides and localizes high-frequency radiation when the beam current Ib ≳ mc3/e≈17 K A. This scheme of plasma guiding of a free-electron laser leads to strong localization of the radiation wave, and to a much higher growth rate for free-electron lasers. © 1990 American Institute of Physics.
