Echo-enabled tunable terahertz radiation generation with a laser-modulated relativistic electron beam
A new scheme to generate narrow-band tunable terahertz (THz) radiation using a variant of the echo-enabled harmonic mh6336gih generation is analyzed.We show that by using an energy chirped beam, THz density modulation in the beam phase space can be produced with two lasers having the same wavelength.This removes the need for an optical parametric a
