Abstract
Based on the single-electron model, the spatial, temporal and spectral emission characteristics of the radiation generated by the electron oscillation driven by a circularly polarized pulse of laser with a FWHM (Full Width at Half Maximum) of 20 femtoseconds and a light intensity at 1020W/cm2 are investigated by theoretical analysis and numerical studies. Electron moves in highly relativistic motion which make it generates an ultrashort radiation about 2.5 attosecond. The numerical results show that the spatial, temporal and spectral distributions in detail of the radiation are sensitively dependent on radiation directions which is neglected by Lee et al. We study a kind of spectral modulation process which has practical significance.
