Intensification of light by an electron beam near an absorbing surface
Oraevskii A. N. , Smetanin I. V.
A fundamentally new scheme is proposed for generating coherent optical radiation. The scheme is based on the amplification of light by a high-current, low-voltage (<l-3 MeV) electron beam near the surface of a resonantly absorbing material. © 1995 American Institute of Physics.
