Abstract

Near-infrared radiation with wavelength around 1000 nm is experimentally observed by coupling a periodical metal grating to the MeV electron beams with high current density generated in the intense ultra short pulse laser and solid target interaction. Simulations prove a prospect of tuning such kinds of radiation into sub-mm waves, which holds a promise for a tunable compact “table-top” powerful Tera-Hertz source.
