The tunability, high power and flexible picoseconds-pulse time structure of terahertz (THz)
radiation make the THz free-electron laser (FEL) a very attractive THz source of coherent …

Optoelectronic techniques for generation and detection of terahertz (THz) signals have been
reviewed. The operation principles of THz photomixer sources and THz parametric sources …

FELiChEM is a new experimental facility under construction at the University of Science and
Technology of China (USTC). Its core device is two free electron laser oscillators generating …

A model of two-stream Free-Electron Lasers (FEL) with an axial guiding magnetic field
(AGMF) is proposed and investigated in this paper. The dispersion relation is derived …

In the early 1980s, the Sagan-Tipler debate raged regarding the interpretation of the Fermi
paradox but no clear winner emerged. Sagan favoured the existence of ETI on the basis of …
