Abstract

Results are presented on the generation of high harmonics through the scattering of relativistic electrons from high-intensity laser light. The characteristic signatures of this process are found to be the emission of even-order harmonics, linear dependence on the electron density, significant amount of harmonics with circular polarization, and small spatial extent of the source. The harmonics are emitted as a forward-directed beam with a divergence of 2°-3°. The measured spatial profile of the harmonics is in excellent agreement with calculations that assume that relativistic electrons play a significant part in the scattering process.
