Abstract

Near-infrared radiation around 1000 nm generated from the interaction of a high-density MeV electron
beam, obtained by impinging an intense ultrashort laser pulse on a solid target, with a metal grating is
observed experimentally. Theoretical modeling and particle-in-cell simulation suggest that the radiation is
caused by the Smith-Purcell mechanism. The results here indicate that tunable terahertz radiation with
tens GV=m ﬁeld strength can be achieved by using appropriate grating parameters
