Abstract

Spatial characteristics of radiation generated from electron oscillations driven by circularly polarized femtosecond laser pulses have been investigated theoretically and numerically using a single electron model. It is discovered that the radiated power is approximately the same in all the directions for the driver laser pulses with low power intensities and the radiation is directed toward the direction of the laser pulses propagation with a narrower divergence and is tipped forward more and more with the increase of laser intensity. The full spatial emission characteristics can be exploited to measure the intensity of circularly polarized laser pulses in the experiment.
