| Abstract: | The dynamics and characteristics of spatial distribution of emission are analyzed with a single electron model in the cases of different intensities and different polarized femtosecond laser pulses. It is discovered that with the increase of laser intensity, for circularly polarized laser pulse, the angular distribution is tipped forward more and more; for linearly polarized laser pulse, the radiation pattern is changed from the fourfold rotational symmetry bifoliate pattern same as that from a dipole antenna to twofold rotational symmetry trefoil pattern. |
