Spatial emission characteristics from electron oscillation driven by a circularly polarized few-cycle laser pulse

Abstract

Full spatial emission characteristics of radiation generated from electron oscillations driven by a circularly polarized few-cycle laser pulse of different intensity have been investigated theoretically and numerically using a single electron model. The effect of laser pulse intensity and the initial phase on the process of full spatial characteristics of the radiation is apparent for few-cycle laser pulse. The characteristics can be used to measure the intensity and the initial phase of a circularly polarized few-cycle laser pulse in experiments.
